Solving Exercise 1 on Page 112 of Math 5 Workbook

Step-by-Step Solution for Exercise 1 on page 112 of Math 5 Workbook

Problem:
Calculate the lateral and total surface area of a cube with a side length of 2m 5cm.

Solution Method:
- Convert the unit of measurement to meters
- Apply the method for calculating the lateral and total surface area of a cube as instructed in Exercise 1 on page 11 of Math 5 Workbook.

Answer:
Convert: 2m5cm = 2.05m
The lateral surface area of the given cube is:
2.05 x 2.05 x 4 = 16.81 (m²)
The total surface area of the given cube is:
2.05 x 2.05 x 6 = 25.215 (m²)
Final Answer: 16.81m²; 25.215m²
