How many cubes with the side lengths of 1/4 cm does it take to fill the prism?

The total number of cubes required is the product of the dimensions in cube-lengths: 3×4×2 = 24 cubes. Step-by-step explanation: 3×4×2 = 24 cubes

so it is 24 cubes

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
