Question

The surface area of the prism is ______ square units. All measurements in the image below are in units. (Input whole number only.) A triangular prism is shown with 2 right triangular sides having legs 6 and 8 and hypotenuse 10. The length of the prism is 6.5 Numerical Answers Expected! Wouldn’t it be 204

Answer 1

this is right prism, we have 90 degrees angle

i have another way

the perimeter is

8+6+10=24

24*6.5=156

the total surface area is 180

the lateral surface area was 156

A=bh+2ls+lb

A=6*10+2(6.5*8)+6.5*6=60+104+39=203

i got 203
