Question

A box is 6 inches wide and 12 inches high. If the volume of the box is 1,242 cubic inches about how long is the box? A. 17 inches, B. 18 inches, C. 35 inches, D. 70 inches

Answer 1

Since the formula for the volume of the cube is width*height*length, we know that 6*12*length=1242. Multiplying it out, we get that 72*length=1242. After that, we can divide 72 from both sides to get 1242/72=length=17.25 inches which I guess is close enough to 17?
