The base of a solid right prism of height 10 cm is a square and its volume is 160 cm3. What is its total surface area of the prism (in cm2)?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 192
TSA of prism = CSA of prism + 2 × area of the base.
The volume of the prism = area of base × height.
160 = area of the base × 10
Area of the base = 160/10 = 16.
Side of the square = = 4.
CSA of prism = Perimeter of base × height
= 16 × 10 = 160.
TSA = 160 + 2 × 16
= 160 + 32 = 192 cm2.
