Question

The volume of a pentagonal pyramid is 32 in. What is the volume if all of the

measures of the pyramid area multiplied by 5?
OA) 160 in 3
OA) 160 in3
OB) 800 in 3
OC) 2000 in3
OD) 4000 in3

Answer 1

OD) 4000

Explanation:

Volume of a pentagonal pyramid = Area of base x height

Since every dimension is multiplied by 5,

Area is multiplied by 5² and height by 5

So volume is multiplied by 5^3 = 125

The volume = 125 x 32 = 4000
