Leonard is going to construct a pyramid with cardboard for math class. Find how many square inches (in.?) of cardboard he will need. Use 4 (2) bh + 67, where b, the base of the pyramid, is 3 in. and h, the height of the pyramid, is 8 in. (1 point)

Answer 1

To find the total surface area of the pyramid, we can use the formula 4(2bh) + b, where b is the base and h is the height.
In this case, b = 3 in. and h = 8 in.
So, the total surface area of the pyramid is 4(2 * 3 * 8) + 3 = 4(48) + 3 = 192 + 3 = 195 square inches. Answer: \boxed{195}.
