a construction worker needs to pour a rectangular slab 23 ft long, 24 ft wide, and 8 in thick. how many cubic yards does the construction worker need?

13.63 cubic yards

Step-by-step explanation:

we are asked to find the volume of the slab in cubic yards, hence we have to be sure that all the lengths are expressed in yards first. We use the following conversions:

1 ft = 1/3 yard

1 in = 1/36 yard

Length = 23 ft = 23 x (1/3) = 23/3 yards

Width = 24 ft = 24 x (1/3) = 8 yards

thickness = 8 in = 8 x (1/36) = 8/36 = 2/9 yards

hence volume = Length x Width x Thickness

= (23/3) x 8 x (2/9)

= 13.63 cubic yards

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
