Question

A decorative wall in a garden is to be built using bricks that are 5 3/4

inches thick and mortar joints that are 1/4 - inch thick. Use the diagram
to find the height of the wall.

Answer 1

The height of the wall is 23¼ inches.

Using the parameters given for our Calculation;

• Number of bricks = 4
• Number of motar joints = 3
• Thickness er brick = 5¾
• Thickness per motar joint = 1/4

The height of the. wall can be calculated thus;

• (Number of bricks × Thickness per brick) + (Number of motar joints × Thickness per mortar join)

Now we have ;

(4 × 5¾) + (3 × 1/4)

23 + 0.75

= 23.75

Therefore, the height of the wall us 23¾ inches .
