Question

A sack of cement is enough to cover a floor with a total area of 45sqft Joel's floor length is 8ft by 7ft how many sacks will he need to cover his entire floor?

Answer 1

2 sack of cement is required to cover Joel's entire floor.

Explanation:

Given:

A sack cement can cover area = 45 sq. ft

Length of Joel floor = 8 ft

Width of Joel Floor = 7 ft

We will first find the Area of Joel's Floor

Area is the Product of length and width.

Area of the Floor =
`length * width`

Substituting the values we get;

Area of the Floor =
`8* 7 = 56\ ft^2`

Now Given:

1 sack of cement cover area = 45 sq ft

Number of sack cement required to cover area = 56 sq. ft.

By Using Unitary method we will find the same.

∴ Number of sack cement required =
`(56)/(45) = 1.24`

Since Sack of cement cannot be in point value hence we can say 2 sack cement is required.

Hence we can say 2 sack of cement is required to cover Joel's entire floor.
