Instructions for Exercise 1 on page 123 of Mathematics Grade 5 Workbook
Problem: A cube with a side length of 2.5cm. Calculate the area of one face, the total surface area, and the volume of the cube.
Solving Method: Step 1: Calculate the area of one face of the cube by multiplying the edge by the edge. Step 2: Calculate the total surface area of the cube by multiplying 6 with a^2 (a is the edge of the cube). Step 3: Calculate the volume of the cube by multiplying the edge by the edge, then multiply by the edge.
Answer: Area of one face of the cube: 6.25cm^2. Total surface area of the cube: 37.5cm^2. Volume of the cube: 15.625cm^3. Solution: 6.25cm^2; 37.5cm^2; 15.625cm^3
