Question

David is making a wall out of bricks. Each brick is 2/3 foot long. There are 20 bricks lined up end to end to make the wall. What is the total length of the wall in inches?

Answer 1

The total length of wall is 160 inches

Solution:

Given that,

`Length\ of\ each\ brick = (2)/(3)\ foot`

1 feet = 12 inches

Therefore,

`Length\ of\ each\ brick = (2)/(3) * 12\ inches = 8\ inches`

There are 20 bricks lined up end to end to make the wall

To find: Total length of wall in inches

`Total\ length\ of\ wall = \text{length of each brick } * \text{ total number of bricks}`

Thus we get,

`Total\ length\ of\ wall = 8 * 20\\\\Total\ length\ of\ wall = 160\ inches`

Thus total length of wall is 160 inches
