Answer:
V= 7.5ft x 4.2 ft x w ft
Step-by-step explanation:
TO find the volume, you follow the expression. height x width x length.
7.5 x 4.2 = 31.5
Next we will use the substituted width of 2.
31.5 x 2 = 63 ft
I would like to say that you can multiply the height, width, and length in any order due to the commutative property.
The GCF of 2 and 4 is 2, so, divide both numbers in the ratio to find the simplified version.
