Find the volume of a rectangular solid 2 feet by 3 feet by 18 inches?

Answer 1

First, simplify the numbers so all three are in equal units. So turn all numbers to inches.

2 ft = 24 in

3 ft = 36 in

and 18 in stays the same.

Then multiply all 3 numbers: 24 in x 36 in x 18 in =

15552 in3

or

If you keep the numbers in feet:

2 ft

3 ft

18 in = 1.5 ft

Multiply all three numbers, again: 2 ft x 3 ft x 1.5 ft =

9 ft3
