The answer is a as-first count the visible ones -15 unit cubes we will need some blocks to support the 2nd 3rd 4th and 5th rows as well....15 4(for the second layer) 6(for the third layer) 6(for the fourth layer 4(for the top layer)=35

So the way of solving it is very easy. First count the visible cubes and count the number of cubes supporting the cubes so it will be 15 4 6 4 6=35. So the answer is A

we can solve this by counting the cubes in the: upper layer which is 1 cubecubes in the second layer =visible cubes in the second layer all the cubes in upper layers=2 1=3cubes in third layer= 3(visible cubes) 3(cubes in upper layers)=6cubes in fourth layer=4(visible cubes) 6(cubes in upper layers)=10cubes in fifth or last layer =5(visible cubes) 10(cubes in upper layers)=15total cubes =1 3 6 10 15=35
