Subject :NSO Class : Class 8
A pile of cubes of equal size is arranged in the form of a block as shown in the figure. If the block is dipped into a bucket filled with red paint, so that only the surfaces of the block get coloured, then how many cubes are coloured on three faces only?
A14
B15
C16
D12
Answer should be 17 cause there are 5 cubes with three faces painted at the top. There are also the 2 corner cubes on the first level that have not been considered in the solution. Pls correct this mistake cause you guys dont correct even a single question. Not expected from you :(
