Jan is making a pencil holder out of plastic canvas. The pencil holder is 4 inches high. It will not have a top. Each edge of the square base is 3 inches long. How much plastic canvas does Jan need?
57
It's 57 :3
It's 57 :V
(4 * 4 * 3) + 3 * 3 = ?
57
Correct, the amount of plastic canvas Jan needs is 57 square inches.
To calculate this, we need to find the area of the base (which is a square with edges of length 3 inches) and the area of the sides (which are rectangles with a height of 4 inches and a length of 3 inches).
The area of the base is 3 x 3 = 9 square inches.
The area of each of the four sides is 4 x 3 = 12 square inches.
So the total area of the sides is 4 x 12 = 48 square inches.
Adding the area of the base and the sides, we get:
9 + 48 = 57 square inches.
