Question

What is the volume of a rectangular crate that has dimensions 9 inches by 9 inches by 1 1/2 feet?

Answer 1

Hello!

To find the volume, use this:
V= w * l * h where w = width, l = length, and h = height

Now even before getting there, you have to convert the units so they are all the same. Let's turn feet into inches
1ft = 12 inches

*NOTE I'm not sure if that says (11/2) or 1 + 1/2, so I'll do both!

If it is (1 + 1/2)
Then turning that into inches will be:
1 + 1/2 = 3/2
3/2 ft * 12in/1ft (since 12 inches/ 1 foot is just 1!)
3*12/2*1 = 36/2 =18 inches.

Now that they are all in inches, multiply!
18in * 9in * 9in = 891 in^3



If it is (11/2)
Turn that into inches:
11/2 ft * 12in/1ft
= 132/2 = 66 inches

Then multiply:
66 * 9 * 9 = 5346 in^3



Hope this helps!

Answer 2

1458 inches cubed. 1 1/2 feet=18 inches 9 times 9 times 18 equals 1458
