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. Wha

Law Incorporation [45]

The total length of wall is 160 inches

Solution:

Given that,

$Length\ of\ each\ brick = \frac{2}{3}\ foot$

1 feet = 12 inches

Therefore,

$Length\ of\ each\ brick = \frac{2}{3} \times 12\ inches = 8\ inches$

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

To find: Total length of wall in inches

$Total\ length\ of\ wall = \text{length of each brick } \times \text{ total number of bricks}$

Thus we get,

$Total\ length\ of\ wall = 8 \times 20\\\\Total\ length\ of\ wall = 160\ inches$

Thus total length of wall is 160 inches
