Bob,
This is what you said to do but i'm still not getting the answer which i have to get to V=20ft cubed. I've done the converting but i can't get to the answer because 4ft is 48inches. I've tried it with feet and inches and i still can't get to the answer please help
The original question is find the volume (v)of a toy box with length(l)of 4ft, iwdth (w) if 24in and height(h) of 30in.Using the formula v=lwh.
The following was your responce from my other postage.
Yes, volume is L x W x H and you have multiplied the numbers correctly; however, the units must be the same. In your problem, the length is 4 FEET but the W and H are listed in INCHES. You must convert feet to inches or inches to feet before multiplying. The ocnversion yo make will depend upon the problem and how it wants the answered; i.e., in cubic inches or in cubic feet.

24 inches = 2 feet.
30 inches = 2.5 feet
Then V = LWH
V = 4 ft x 2 ft x 2.5 ft = 20 ft^3.
If we work in inches, then
4 ft x 12in/ft = 48 inches and
48in x 24in x 30in = 34,560 in^3. Then to show these are the same answer, the conversion from cubic inches to cubic feet is 1,728 in^3 = 1ft^3 and
34,560/1,728 = 20 ft^3
I hope this helps.
