To find the total volume of the sandbox, we multiply the height (1/2 ft) by the area of the base (b ft^2). Therefore, the inequality for the area of the base, b, of the sandbox that must contain at least 42 cubic ft of sand is:
(1/2) * b ≥ 42
Simplifying: b ≥ 84
A sandbox in the shape of a rectangular prism is 1/2ft. high and needs to contain at least 42 cubic ft of sand. How would you write an inequality to express the possible area of the base, b, of the sandbox?(1 point)
