Question

The length of base edge of a square prism is 8 cm and its height is 10 cm.
Find the total surface area of the prism.
a) Base area of the prism
b) Area of one lateral face of the prism
e) Number of bases
a) Number of lateral faces
e) Total surface area of the prism = 2 x base area + lateral surface area​

Answer 1

Given,

The base edge of prism = 8 cm

Height = 10 cm

To find,

Total surface area of the prism.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

The base area of the prism :

= (8×8) cm² [As, it is a square]

= 64 cm²

Area of lateral face of the prism :

= (8×10) cm² [As, it is a rectangle]

= 80 cm²

Number of bases = 2

Number of lateral faces = 4

Total surface area = 2 x base area + lateral surface area = (2×64) + (4×80) = 128+320 = 448 cm²

Hence, the TSA of prism 448 cm².
