Answer 2

Help

Answer 3

So first you find the area of each side.
S1=3x4
S2=4x5
S3=5x3

Answer 4

so the sides are
S1=12
S2=20
S3=15

Answer 5

So because there are two of each side you multiply each side by two.
12x2
20x2
15x2

Answer 6

so you then add all of the sides together\[24+40+30\]

Answer 7

So your answer is C \[94m ^{2}\]

Answer 13

I think it is 288

Answer 14

okay so there are two different sides the square base and the triangles. the square base is a 6 by 6 base so the area of that is 36. the triangle base is and 8 by 6 so you multiply 8 and 6 and divide the answer by two which is 24. but because there are four triangles you multiply 24 by four which is 96. So you then add 96 and 36 which is 132 so the answer is \[132cm ^{2}\]

Answer 15

What is the surface area of the square pyramid?

Answer 17

So for the square base you multiply 38 by 38 which is 1444. For the triangles you multiply 38 by 42 and divide it by two which is 798. You then multiply 798 by 4 which is 3192. After that you add 1444 and 3192 so the answer is C\[4636\in ^{2}\]

Answer 20

So for this you have a side of 10 and 5 so the area is 50. Another side is a side of 18 and a side of 8 so the area is 80. The last side is 8 and 5 so the area is 40.

Answer 21

so you take each side and multiply it by two
50x2=100
80x2=160
40x2=80

Answer 22

you then add all of the sides \[100+160+80=340\]

Answer 23

so the answer is \[340ft ^{2}\]
