Find the height of the right rectangular prism Solutionright

Find the height of the right rectangular prism.

right rectangular prism surface area S = 2 ( wh + lw + lh )

l = 6 ft , w = 4 ft , h = h and S = 108 ft^2

Substituting in the formula , we get

108 = 2 (4h + 24 + 6h)

=> 108 = 2 (10 h + 24 )

=> 10 h + 24 = 108/2

=> 10 h + 24 = 54

=>10 h = 54-24

=> 10 h = 30

=> h = 3 ft. is the height of the right rectangular prism .
