We can see that
There are four triangle on the surface
and five squares
For finding surface areas , we will find area of each surface and then add them
Calculation of area of triangle:
We are given
base=b=8
height=h=10
now, we can use area formula



Calculation of area of square:
base=width=8


There are four triangle and five squares on the surface
so, we can find surface area
SA=4* triangle + 5*square


so, surface area is
