Homework Help: math

Using this formula:
V=LWH

Find the volume(v)of a toy box with length (L) if 4ft, width(W)of 24in.,and height(H)of 30in.

My answer:Wouldn't it be the following;

V=(4)(24)(30)
V=2888

Please let me know if I am correct. I believe that the formula is V=L*W*H isn't it. Please help me solve it out if I'm wrong.

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.
