To find the amount of cardboard Leonard will need, we need to calculate the surface area of the pyramid.
Using the formula given: 4(12)bh + b^2,
we can substitute the given values:
4(12)(3)(8) + 3^2
Simplifying the equation:
4(12)(24) + 9
1152 + 9
The total amount of square inches of cardboard Leonard will need is 1161 in.2.
