Question

A rectangular prism has a length of 2\1\2 centimeters, a width of 2\1\2 centimeters, and a height of 5 centimeters. Justin has a storage container for the prism that has a volume of 35 cubic centimeters. What is the difference between the volume of the prism and the volume of the storage container? Enter your answer in the box as a simplified mixed number or a decimal. cm³

Answer 1

l = 2.5 cm
w = 2.5 cm
h = 5 cm
d = 6.12372 cm
S = 62.5 cm2
V = 31.25 cm³ 

35 cm³- 31.25 cm³ = 3.75 cm³  <- Answer

Answer 2

V(prism) =  2 1/2 squared (l*w) * 5
   = 6.25 * 5
   = 31.25
V(prism) = 31.25 centimeters cubed
V(container) - V(prism)
35 - 31.25 = 3.75
The difference in volume is 3.75 cubic centimeters.
