if 1 gallon for 12 miles
how many gallons for 324 miles
?.12=1.324
?=324/12
?=27 miles
By definition, the volume of a rectangular prism is given by:
V1 = (w) * (l) * (h)
Where,
w: width
l: long
h: height
Substituting we have:
60 = (w) * (l) * (h)
if the length and the width double, and the height remains the same, we have:
V2 = (2w) * (2l) * (h)
Rewriting:
V2 = 4 * ((w) * (l) * (h))
V2 = 4 * V1
Substituting we have:
V2 = 4 * (60)
V2 = 240 cubic feet
Answer:
the new volume will be:
V2 = 240 cubic feet
