Math, microeconomics or criminal justice
top, the ramp side = 10x4 = 40 ft^2
the shaded side = 6(8)/2 = 24 ft^2
the opposite unseen side also = 24 ft^2
another unseen side is 6x4 = 24 ft^2
That sums to 112 ft^2
But if you wanted to paint the bottom, that's another 8x4 = 32 ft^2
summing it all is 144 ft^2
