Right-angled 6034

A three-sided prism has a base in the shape of a right-angled triangle with a length of 5 cm. The giant wall of the prism shell has a volume of 104 cm2. The prism is 8 cm high. Calculate the volume and surface area of ​​the prism.

Correct answer:

V =  240 cm3
S =  300 cm2

Step-by-step explanation:

a=5 cm h=8 cm S1=104 cm2  c=S1/h=104/8=13 cm b=c2a2=13252=12 cm S2=a b/2=5 12/2=30 cm2 V=S2 h=30 8=240 cm3
S3=(a+b+c) h=(5+12+13) 8=240 cm2 S=2 S2+S3=2 30+240=300 cm2
