Question

Find the volume and surface area.

Answer 1

Answer: Formula used for pyramid is (V= 1/3 Bh SA: 1/2 P*l+B) Final answer is SA=110.4 V=64

Explanation:

P= Perimeter

l= length

B= Base

To find the perimeter you add all the sides of the base. (4+4+4+4)=16

To find the length you can use Pythagorean Theorem which is a(squared) + b(squared) = c(squared) where c is the hypotenuse.
`2^(2)` +
`12^(2)`=
`x^(2)`

4+144=
`x^(2)`

164=
`x^(2)`

`√(164)`=x

x=12.8

To find the base it will be l*w (4*4)=16

Then you plug it in the formula for SA which will be

SA=1/2 16*12.8+16

SA=110.4

For Volume, it will be

V=1/3 Bh

V= 1/3 16(12)

V= 64
