Question

6. A square based pyramid is placed on a square based prism with the same
base 14 cm. If the height of the priam to 9 cm and height of the pyramid is
7 cm, find the total surface area of the solid obtained by joining them.​

Answer 1

Step-by-step explanation:

TSA of solid = TSA square base pyramid + TSA of prism

TSA of pyramid = 4×

= (2×7

×14)+196

= 196(

= 472.36cm

2

TSA of Prism =LSA+2(areaofbase)

= (Perimeter of base × h) + 2(14)

2

= (4×14×9)+392

= 504+392=896cm

2

∴ TSA of solid =472.36+896 = 1368.36cm
