The base of a lamp is solid glass in the shape of a square prism. Each side of the square measures 5 in. If 300 in, of
glass were used to make the lamp's base, what is the height

Answer 1

`h=12.5\ in`

Explanation:

we know that

The surface area of a square prism is given by the formula

`SA=2(b^2)+4bh`

where

b is the length side of the square base

h is the height of the prism

we have

`b=5\ in\\SA=300\ in^2`

substitute

`300=2(5^2)+4(5)h`

solve for h

`300=50+20h\\20h=300-50\\20h=250\\h=12.5\ in`
