Right-angled triangle base

Find the volume and surface area of a triangular prism with a right-angled triangle base if the length of the prism base legs are 7.2 cm and 4.7 cm and the height of a prism is 24 cm.

Correct answer:

V =  406.08 cm3
S =  525.7981 cm2

Step-by-step explanation:

a=7.2 cm b=4.7 cm h=24 cm  S1=2a b=27.2 4.7=25423=16.92 cm2  V=S1 h=25423 24=25423 24=2510152=2510152 cm3=406.08 cm3
c2 = a2 + b2 c=a2+b2=7.22+4.728.5983 cm  p=a+b+c=7.2+4.7+8.598320.4983 cm  S=2 S1+p h=2 16.92+20.4983 24=525.7981 cm2
