the answer for the parrallelogram should be 48 cm^2 because you multiply 8 times 6 making the answer 48.
The answer for the triangle for the area should be 12 because the formula for finding the area of the triangle is 0.5 times base times height.
the answer for the missing dimension of the triangle should be 10 making the answer 10.
the answer for the area of the triangle should be 6 because you multiply 0.5 or 1/2 times 4 times 3 making the answer to be 6.
the answer for the last one should be 90 because you do as i did multiplying 0.5 or 1/2 times 9 times 20 making the answer to be 90.

What is the total surface area of the figure?
Answers
Answer:
531 in²
Step-by-step explanation:
5 faces of the cube are facing the surface because the top one is shared with the triangular prism.
Surface area of a cube is S = 5 × (9)²
S = 405 in²
Now the triangular prism: S = (1/2)lP + B, where l is slant height and p is the perimeter of the base. (ignore B base area because this is also not facing the surface/shared with the cube).
S = (1/2)7×(4×9)
S = 126 in²
Add 126 + 405 to get 531 in²

Jacob is building a square pyramid for a class project. He needs to cover the entire pyramid in aluminum foil. The base of the pyramid has a perimeter of 76 centimeters. The slant height of each triangular side is 28 centimeters. What is the surface area, in square centimeters, of Jacob's pyramid?
Answers
Answer:
The surface area of Jacob's pyramid is 1425cm²Step-by-step explanation:
Step 1
Find the dimensions
We will be finding the dimensions to find the surface area. We know on what is the perimeter of the square base, and what is the slant height of each triangle. So that's enough to know, if we know the perimeter, of the square base, we can divide that by 4 to get our 1 side's length. Then, we can calculate the square base's SA and the Triangle's SA!
76/4=19
Now we have our dimensions ready!
Square Base each side length: 19 centimeters
Triangle slant height for each single: 28 centimeters
Step 2
Figure out the SA's now!
Now, let's figure out all the SA's.
First the square base!
19x19=361cm²
Now, let's figure out the SA for all of the triangles
As we know, to find the Area or Surface Area (SA) of each triangle, we have to use this formula:
[tex]SA=\frac{1}{2} *B*H[/tex]
But to find the surface area of 4 triangles at once, we will have to use this formula:
[tex]SA=2*B*H[/tex]
Let's do it now!
[tex]SA=2*19*28\\=2*532\\=1064[/tex]
1064cm²
Step 3
Add all the SA's up to get FINAL ANSWER!

Step-by-step explanation:
Your a (base) is 4, which is A-P.
Your b (base) is 1, which is T-R.
Your h (height) is 3, which is the distance from the bottom of the trapezoid to the top.
Then you plug it into your formula, A = (a + b) x h/2 (A = (4 + 1) x 3/2)
That equals 7.5.

to find the persentage of a number, you can first devide the whole number by 100, then multiply by the persentage ur figuring out, heres an example
for 24% of 33.50. we first devide 33.50 by 100
33.50 / 100 = 3.35
then multiply by 24

A standard die is a cube with sides measuring 15 mm. What is the volume of the die?
Answers
Answer:
3375mm^3
Step-by-step explanation:
15*15=225
225*15=3375
3375mm^3 is the volume of the die.
Answer:
3,375mm²
Step-by-step explanation:
Since each side of a cube is the same length, that means that we will just have to do 15mm*15mm*15mm to get our answer.
V = L x W x H
= 15 x 15 x 15
= 3,375
Hence, the volume of the die is 3,375mm²
