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!
