Question

what is the total surface area of a right triangular prism whose altitude is 15cm long and whose base is a right angled triangular with lengths of sides 6cm, 8cm and 10cm?​

Answer 1

Answer:

408cm²

Step-by-step explanation:

Total Surface Area of a right prism = 2B + ph, where B = area of the base, p = perimeter of the base and h is the vertical height.

B = (1/2)ab = (1/2)(6)(8) = 24 cm².

p = 6+8+10= 24

h = 15 given

So TSA = 2(24) + (24)(15) = 408 cm²
