It takes x liters of paint to paint a 4*4*4 cube completely. If the cube is broken into 8 smaller cubes, then find the paint required to paint all them completely
Answer: (2) 2x Solution: original surface area = 6 surfaces of 4*4 = 96 squnit 8 smaller cubes of 2*2*2 , each surface area = 6(2*2) = 24 total surface area of 8 cubes = 24*8 = 192 squnit Hence total paint required = 2x
