Question

the base of a triangular prism with sides 3 cm 4 cm and 5 cm . find the volume of the prism if its height is 20 cm

Answer 1

Thank you for asking this question, here is your answer:

So  first of all we will look at the area

and we know that area of triangle is 1/2 b h

And the area of 3rd angle is 1/2 (3) (4)

The answer of that would be 6cm²

Now we will use this formula:

area of prism is area of base ×height

and that would be

6×20

= 120cm³

So the final answer for this question is 120cm³
