Can you help me to figure out how many pieces of 1.5 cm × 2 cm chocolate can I cut from a 18 cm × 18 cm sheet of chocolate?
Solution:
Given, the dimensions of a chocolate sheet is 18 cm × 18 cm.
Chocolate pieces of dimensions 1.5 cm × 2 cm is cut out from the sheet.
We have to find the number of pieces that can be cut out from the sheet.
The chocolate sheet is in square shape
Area of square = (side)²
Area of chocolate sheet = 18 × 18
= 324 cm²
Chocolate pieces represent rectangular shape
Area of rectangle = length × breadth
Area of chocolate piece = 1.5 × 2
= 3 cm²
Number of pieces = area of chocolate sheet / area of chocolate piece
= 324/3
= 108
Therefore, the number of chocolate pieces is 108.
