Question

3.6m by 1.8 m wall How many 6 cm by 6 cm pictures could fit on the wall?

Answer 1

(3.6*100)/6=60
(1.8*100)/6=30
60*30=1800
there are 1800 pictures could fit on the wall.

Answer 2

1800 pictures could fit on the wall.

Explanation:

If the area of a space is given as A and this space is to be filled by pictures of area A' then number of pictures will be =
`(A)/(A')`

Now we know area of wall is A and area of picture is A'.

Length and width of wall = 3.6×1.8 m

So area of the wall A = 3.6×1.8 = 6.48 m²

Dimensions of one picture = 6×6 cm Or 0.06×0.06 m

So are of one picture A' = 0.0036 m²

Therefore, Number of pictures on the wall =
`(A)/(A')` =
`(6.48)/(0.0036)=1800`

Number of pictures required to cover the wall = 1800
