Question

a giant pizza box in the shape of a rectangular prism measures 38m times 38m times 0.25m. what is the surface area of the box

Answer 1

So this box will probably be very flat. Draw it out. There would be 4 surfaces with the surface area of 0.25*38. Which equals 9.5. Multiply that by 4 and it's 38. Now take the bigger surfaces. They will be 38 squared, which is 1444. Multiply that by 2, because there are 2 of those surfaces, and you get 2888. To get the total you add them up: 38+2888=2926. So the answer is 2926 meters squared.

Answer 2

So the surface area of a box has this equation: A = 2 (wl + hl + hw)

w = width = 38
l = length = 38
h = height = 0.25

Plugging in:
A = 2 ((38*38) + (38*0.25) + (38*0.25))
    = 2926 square meters
