Question

What is the surface area of the following prism?

Answer 1

Answer:

102cm²

Step-by-step explanation:

Surface Area = BH +Lp

B is the base area

H is the height of the Prism

L is the slant height

p is t perimeter of its base

B =1/2 ×3×4

B= 6cm²

H = 7cm

L = 5cm

P = 3cm+4cm+5cm

P = 12cm

Substitute

TSA = 6(7)+5(12)

TSA = 42+60

TSA = 102cm²

Hence the total surface area of the shape is 102cm²
