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.

To solve the problem, you need to convert the units to be consistent.

If you want the answer to be in cubic inches, you need to convert the length from feet to inches. Since there are 12 inches in a foot, the length of 4 feet would be 4 * 12 = 48 inches. Then you can use the formula V = LWH as follows:

V = (48 inches) * (24 inches) * (30 inches)
V = 34,560 cubic inches

If you want the answer to be in cubic feet, you need to convert the width and height from inches to feet. Since there are 12 inches in a foot, you divide the width and height by 12.

V = (4 feet) * (24 inches / 12) * (30 inches / 12)
V = (4 feet) * (2 feet) * (2.5 feet)
V = 20 cubic feet

So depending on the unit you want the answer to be in, the volume of the toy box is either 34,560 cubic inches or 20 cubic feet.
