Question

How many squaue tiles of side 8cm willbe needed to tile a floor which is 400cm long 160cm wide

Answer 1

Answer:

The number of square tiles will be 1000

Step-by-step explanation:

• Length of side of the square tiles=8 cm
• Dimension of the floor.400 cm long and 160 cm wide

We know that area of square of side a is given by, A=$a^2$

So the area that one tile will cover on the floor=$8^2=64\ \rm cm^2$

The total area of the floor is given =$=400\times160\ \rm cm^2\\\\=64000\ \rm cm^2$

The total number of required tiles will be equal to the total area of the floor divided by the area of one tile. Let n be the number of tiles then

$n=\dfrac{64000\ \rm cm^2}{64\ \rm cm^2}\\\\n=1000$

Hence the the total number of times is calculated.
