B=144

Hiii kumarr

Kitne sahi hue ajj

Hi kumar

hey can any one tell me in 9 prob 2nd step how it came

Kitne means how,,,ann means hear na

thanks mam

let side be 3x, 4x & 5x

then perimeter =12x

height = 6 cm^2

lateral area of prism= perimeter* height

144 = 12x*6

x=144/12*6

x=2

Base area = (1/2)base* height

= (1/2)*4x*3x =(1/2)12 x^2

=(1/2)12*4

=24 cm^2

volume of prism V=(Base Area)*Height

V=24*6

V= 144 cm^3
