Solution:

<u>Note that:</u>

  • Surface area = Area of all faces

<u>Finding the area of the two triangles</u>

  • 2(1/2 x 8 x 6)
  • => 8 x 6
  • => 48 ft²

<u>Finding the area of rectangle₁</u>

  • 12.6 x 10
  • => 126 ft²

<u>Finding the area of rectangle₂</u>

  • 12.6 x 6
  • => 75.6 ft²

<u>Finding the area of rectangle₃</u>

  • 12.6 x 8
  • => 100.8 ft²

<u>Finding the surface area of the figure</u>

  • 48 + 126 + 75.6 + 100.8
  • => 350.4 ft²

What is the difference in surface areas, in square feet, of the two boxes?
Katarina [22]
The difference is 3ft since the surface area for the prism is 57, and the surface area for the cube is 54.

You can use the surface area formula
2(wl+hl+hw) = Area
2·(3·4.5+2·4.5+2·3)=57

And a cubes surface area formula
6a^2 = Area
6·32=54
