The surface area of the bigger rectangle is:
- Two sides are 6 by 11: 2(6 x 11) = 132
- Two sides are 3 by 11: 2(3 x 11) = 66
- Two sides are 6 by 3: 2(6 x 3) = 36
Adding these together: 132 + 66 + 36 = 234
The surface area of the smaller rectangle is:
- Two sides are 2 by 3: 2(2 x 3) = 12
Adding the surface area of the two rectangles together: 234 + 12 = 246
Therefore, the total surface area of the shape is 246.
What is the surface area of the shape?
A bigger rectangle that is 6 by 3 by 11 with a smaller rectangle that is 2 by 3
