A sandbox in the shape of a rectangular prism is 12ft. high and needs to contain at least 42 ft.3 of sand. How would you write an inequality to express the possible area of the base, b , of the sandbox?(1 point)

≥ 3.5 ft²
fix the answer
The volume of a rectangular prism is given by V = lwh, where l is the length, w is the width, and h is the height. In this case, the height is 12 ft and the volume is at least 42 ft³.

So the inequality to express the possible area of the base (b) of the sandbox would be:

b ≥ 42/(12*3.5)

b ≥ 1 ft²
