Question

Find the surface area of the rectangular prism.
7 km
5 km
3 km

Answer 1

`142km^(2)`

Explanation:

you need to find the area of every side and then add them all together so

you do the equation

`2[(7*5)+(3*5) + (7*3)]`

I multiply everything by 2 because there is 2 of every side

once you solve this you get the answer of
`142km^(2)`

Answer 2

142 km^3

Explanation:

A=2(wl+hl+hw)

A=2(7*5+3*5+3*7)

A=142
