Monica is constructing a box in the shape of a right rectangular prism to hold grain on her farm. Use the formula for the volume of a rectangular prism to find the area of the base when the volume is 50 cubic feet and the height is 4 feet.
The formula for the volume of a rectangular prism is V = lwh, where V is the volume, l is the length, w is the width, and h is the height.
In this case, we are given the volume as 50 cubic feet and the height as 4 feet. Plugging these values into the formula, we have:
50 = lw(4)
To find the area of the base, we can solve for l and w. First, divide both sides of the equation by 4:
50/4 = lw
12.5 = lw
Now, we have an equation for the area of the base:
Area of the base = lw
Substituting the value of 12.5 for lw, we get:
Area of the base = 12.5 square feet. Answer: \boxed{12.5}.
