If you multiply the Length of a Concrete Floor by its Width: Which one of these will you have discovered.

• Volume ?

• Perimeter ?

• Depth ?

• Area ?

The surface Area of a Concrete Oversite can be Calculated by using the following formula:

• (L x W) "Length multiplied by the Width"

• (L x W x D) "Length multiplied by the Width, multiplied by the Depth"

• (L + W X 2) "Length multiplied by the Width, Multiplied by Two)

• 2(L X W) "Length multiplied by the Width, Multiplied by Two"

What does this symbol mean:

• ADD ?

• SUBTRACT (Take away) ?

• DIVIDE ?

• MULTIPLY ?

If I wanted to work out how many Concrete Paving Slabs I had I could:

• Add them up ?

• Multiply them up ?

• Divide them up ?

• Subtract them up ?

If I was working out how many Concrete slabs I had, which symbol would I be using:

• 
• 
• 
• 

There are 20 Concrete Slabs in each banded pack. I have 9 packs. How could I work out the total; all of the slabs that I have:

• Multiply 20 by 9 ?

• Divide 9 by 20 ?

• Subtract 9 from 20 ?

• Add 9 and 20 together ?

Each one of these Paving Slabs measures 900mm by 900mm. How could I work out the Area of each Slab:

• Add all of the sides together ?

• Add 2 sides then multiply it by 2 ?

• Divide 900mm by 900mm ?

• Multiply 900mm by 900mm ?

Calculate the area of one Concrete Slab. The Slab measures: 900mm by 900mm:

• 0.81 square millimetres ?

• 0.081 square millimetres ?

• 8.10 square millimetres?

• 81.00 square millimetres ?

I need to build a path like this one. The new path will be 9 metres long. Each Concrete Slab is 900 millimetres long. There are two side by side. How many Concrete Slabs do I need to order:

• 20 ?

• 10 ?

• 30 ?

• 15 ?

You are building a Garden Path using one row of 900mm by 900mm Concrete Paving Slabs. The path has a Brick edge on both sides. Each Brick is .225mm long. You will need 9 Slabs. How many Bricks will be required:

• 9

• 18

• 71

• 45
