Step-by-step solution for Exercise 2 on page 110 in Math 5 workbook

Problem:
A rectangular open box has a length of 1.5m, width of 0.6m, and height of 8dm. The exterior surface of the box is being painted. What is the painted area in square meters?

Solution Method:
Refer to the detailed guide in solving Exercise 1 on page 110 of Math 5 Workbook.

Answer:
    8dm = 0.8m
The painted area of the box is:
    (1.5 + 0.6) x 2 x 0.8 = 3.36 (m²)
The base area of the box is:
    1.5 x 0.6 = 0.9 (m²)
The painted area is:
    3.36 + 0.9 = 4.26 (m²)
              Answer: 4.26m²
