Question

A regular triangular prism is 5m. height, the perimeter of the base which is an equilateral triangle is 3cm. Find the volume of the prism​

Answer 1

Answer:

4√3/5 cu cm

Step-by-step explanation:

perimeter of the base which is an equilateral triangle is 3cm

let side of equilateral triangle = a

3*side=3a=3 cm

side = a = 3/3 =1cm

area of equilateral triangle= (√3/4 )a^2

=√3/4 sq cm

height=5 cm( but you have given as 5 m once check)

area of prism area of base * height

= √3/4 * 5

=5√3/4 cu cm

if h= 5m= 500 cm

volume= 500√3/4 cu cm
