Question

Observe the composite figure below.
The bottom shape is a cube with base edges of 6 inches. The top shape is a right pyramid with a height of 4 inches. What is the surface area of this composite figure?

Answer 1

Figure vv

Answer 2

basically surface area of cube = 6*side^2
surface area of pyramid= 2*slant height*side +side^2

but notice here that they have one face in common

so surface area of cube = 5*side^2
surface area of pyramid= 2*slant height*side

and then you add them
note:
slant height^2 = 4^2+3^2
slant height = 5

Answer 3
