A right prism has a rectangular base with dimensions 6 cm and 10 cm. The height of the prism is 18 cm. Find the total surface area of the prism.
Show answer & explanation
Correct answer: A
Explanation
Length = 10 cm
Width = 6 cm
Height = 18 cm
Total surface area of the rectangular prism -
= 2 × (lb + bh + hl)
= 2 × (10×6 + 6×18 + 18×10)
= 2 × (60 + 108 + 180)
= 2 × 348
= 696 square centimeters
