The weight of the rectangular prism block of gel is: 22.5 pounds.
What is the Volume of a Rectangular Prism?
Volume = length × height × width
The block of gel is a rectangular prism.
Given that the gel weighs 54 pounds per cubic foot, first, find the volume of the block of gel in cubic ft.
Length = 20 in. = 1.67 ft
Height = 6 in. = 0.5 ft
Width = 6 in. = 0.5 ft
Volume = 1.67 × 0.5 × 0.5 = 0.4175 cubic ft.
Thus:
1 cubic foot = 54 pounds
0.4175 = (0.4175 × 54)/1
= 22.5 pounds.
Thus, the weight of the rectangular prism block of gel is: 22.5 pounds.
