The area of any right polygon can be found out by the formula

Base area X height
For this question as well we can use this formula.
Base area of the triangle is 6cm^2
and the height is 10 cm
Therefore the volume will be 6X10=60 cm^3

Questionbook123: How do you get base area as 6.Could you explain it briefly.

itzzkushagra: Ya! We know that the sides of the triangle are 3,4,5 and 3,4,5 is a Pythagorean triplet. That is the base triangle is a right angled triangle with base =3 and height = 4 therefore the area of the triangle is 1/2 base×height = 1/2 × 3 × 4 = 6cm^2
