You're on a roll — here's the solution for question 4. Question 4: The 6 faces of a solid cube of length 3 m is to be painted. The painting cost is Sh. 150 per square metre. Find the total cost of painting the cube. Step 1: Identify the side length of the cube. The side length of the cube is s = 3 m. Step 2: Calculate the total surface area of the cube. The formula for the total surface area of a cube is 6s^2. Total surface area = 6 × (3 m)^2 = 6 × 9 m^2 = 54 m^2 Step 3: Calculate the total cost of painting. The cost of painting is Sh. 150 per square metre. Total cost = Total surface area × Cost per square metre = 54 m^2 × Sh. 150/m^2 = Sh. 8100 The total cost of painting the cube is Sh. 8100.
