Question

A box has dimensions of 15 inches long, 3.1 feet wide, and 7 inches high. What is the volume of the box? The formula for the volume is V = l · w · h. 325.5 in3 976.5 in3 3,906 in3 39,060 in3

Answer 1

the volume of the box is: 3906 in^3

Explanation:

Length of the box(l)=15 inches

width of the box(w)=3.1 feet

as all the units must be same so we will convert feet into inches.

we know that 1 foot=12 inches

3.1 feet=3.1×12 inches

3.1 feet=37.2 inches

height of the box(h)=7 inches

volume of the box(V)=l×w×h

=15×37.2×7 inches^3

=3906 inches^3.

Hence, the volume of the box is:3906 in^3

Answer 2

The answer choices are in cubic inches, so convert the dimension that is given as feet into inches.

1 foot = 12 inches, so multiply 3.1 feet by 12:

3.1 x 12 = 37.2 inches.

Now multiply the three dimensions to find the volume:

15 x 37.2 x 7 = 3,906 in^3
