Answer:
The number of blocks that will be needed to build the wall is 2500
Step-by-step explanation:
The number of blocks that will be needed to build the wall is;
[tex]n = \frac{volume of wall}{volume of block} \\volume = l *b*h\\[/tex]
given the dimensions of the block and wall as;
block = 22cm by 11cm by 7cm
wall = 5 1/2m long, 22cm thick and 3 1/2m high. = 550cm by 22cm by 350cm
substituting into the equation, we have;
[tex]n = \frac{volume of wall}{volume of block} \\volume = l *b*h\\\\n = \frac{550*22*350}{22*11*7} \\n = 2500[/tex]
The number of blocks that will be needed to build the wall is 2500
