A rectangular pyramid. The rectangular base has a length of 10 centimeters and a width of 2 centimeters. 2 triangular sides have a base of 2 centimeters and a height of 8 centimeters. 2 triangular sides have a base of 10 centimeters and a height of 6.3 centimeters.
What is the surface area of the rectangular pyramid shown?

99 cm2

Step-by-step explanation:

1. to break this up a bit first find the area of the base

10*2 = 20

2. now 2 triangular sides with the base of 2

2*8/2= 8 (each triangle is 8 cm2)

there's two of them so it's 16

3. now the last two triangular sides

10*6.3/2=31.5

there's two of them so it's 63

4. add it all up: 20 + 16 + 63 =99
