Volume of a rectangular prism = length x width x height
Given that the height is 12 ft and the volume of the sandbox is at least 42 ft^3:
42 ft^3 ≤ b x w x 12 ft
Divide by 12 ft on both sides:
3.5 ft ≤ b x w
Therefore, the inequality to express the possible area of the base, b, of the sandbox is:
3.5 ft ≤ b x w
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)
