Triangular prism

Calculate a triangular prism if it has a rectangular triangle base with a = 4cm and hypotenuse c = 50mm, and the height of the prism is 0.12 dm.

Correct answer:

V =  7.2 cm3
S =  26.4 cm2

Step-by-step explanation:

a=4 cm c=50 mm cm=50:10  cm=5 cm h=0.12 dm cm=0.12 10  cm=1.2 cm  b=c2a2=5242=3 cm  S1=2a b=24 3=6 cm2  V=S1 h=6 56=56 6=536=536 cm3=7.2 cm3
o=a+b+c=4+3+5=12 cm  S=2 S1+o h=2 6+12 56=26.4 cm2
