Answer:
Increase
Step-by-step explanation:
Since the total number of blocks in a pyramid is found by dividing the height of pyramid by the height of each block, then the block height of 1.39 m requires more pieces compared to 1.4 m
Illustration
If the height of pyramid was 139 m, the number if blocks each measuring 1.39 m will be 139/1.39=100+1 blocks while if blocks are 1.4m then number will be 139/1.4=99+1 blocks
Therefore, the height of 1.39m will increase the number of blocks
