A typical graph sheet is 18cm by 24cm. The smallest square on the sheet has an area of 1mm^2. How many of these 1mm^2 squares are on the sheet of graph paper?
18 cm = 180 mm
24 cm = 240 mm
A = 180 * 240
A = ?
To determine how many 1mm^2 squares are on the sheet of graph paper, we need to find the area of the sheet and divide it by the area of each square.
First, let's convert the dimensions of the sheet to millimeters:
18 cm = 180 mm (since 1 cm = 10 mm)
24 cm = 240 mm
Now, let's calculate the area of the sheet:
Area = length x width = 180 mm x 240 mm = 43,200 mm^2
Next, we need to calculate the area of each 1mm^2 square:
Area of each square = 1 mm^2
Finally, we can divide the area of the sheet (43,200 mm^2) by the area of each square (1 mm^2) to find the number of squares that fit on the sheet:
Number of squares = Area of sheet / Area of each square = 43,200 mm^2 / 1 mm^2 = 43,200 squares
Therefore, there are 43,200 of these 1mm^2 squares on the sheet of graph paper.
