Question
The base of a solid right prism is a triangle whose
sides are 7cm, 24cm and 25cm. the height of the prism is 5 cm then the total surface area of the prism is?Solution
As 7, 24 & 25 is satisfying Pythagoras so it is a right angle triangle. Total surface area of prism = Perimeter of base× Height + 2 × Area of base = (7 + 24 + 25) × 5 + 2 × (1/2 × 7 × 24) = 56 × 5 + 2 × 84 = 280 + 168 = 448 cm 2Â

a – b = 5
ma – 4b = 1
