First, we find the volume of the gel which is a rectangular prism in shape: V=lwh
V=(20)(6)(6)
V=720 cubic inches
Then, we convert this cubic foot. Since 1ft=12in., then (1ft)3=(12in.)3 or 1ft3=1728in.3 so:
V=720 cubic inches×(1 cubic foot/1728 cubic inches)=5/12 cubic foot
We find the weight of the gel by multiplying the density by the volume:
(54 pounds/cubic foot)×5/12 cubic foot=22.5 pounds
