You have to use the formula for volume of triangular prism

mmk

anonymous · Answer

if not mistaken volume for triangular prism should be V=1/2 * bhl=5. b= base length, h= height, l= length between 2 triangles. for the new volume, Lets say A. A=1/2 * (3b)(3h)(3l)=(1/2)bhl(3^3)=5*27=135. so i think the answer would be 135.
