Answer
3. Solve Exercise 3 - Math exercise book for 5th grade on page 22
Problem Statement:
Given a rectangular box (see the adjacent figure).
a. Complete the blanks appropriately:
DQ = AM = ..... = .....
AB = MN = ...... = .....
AD = BC = ..... = .....
b. Given the length is 7cm, width is 4cm, and height is 5cm. Calculate the area of the base ABCD and the lateral surfaces DCPQ, AMQD
Solution Method:
- Observe the illustration and determine equal edges based on the properties of a rectangular box.
- The base ABCD and the lateral surfaces DCPQ, AMQD are all rectangles.
Calculate the areas of the shapes using the formula: area of a rectangle = length x width.
Answer:
a. Fill in the blanks appropriately:
DQ = AM = BN = CP
AB = MN = PQ = DC
AD = BC = NP = MQ
b. Calculate the area of the base ABCD:
7 x 4 = 28 (cm2)
Calculate the area of the lateral surface DCPQ:
7 x 5 = 35 (cm2)
Calculate the area of the lateral surface AMQD:
4 x 5 = 20 (cm2)
Answer: Area of the base ABCD 28 cm2; Area of the lateral surface DCPQ 35 cm2; Area of the lateral surface AMQD 20 cm2
4. Solve Exercise 4 - Math exercise book for 5th grade on page 23
Problem Statement:
Mark 'x' in the empty box below the rectangular box, and mark in the empty box below the square pyramid:
Solution Method:
Observe the diagram and rely on the properties of a rectangular box and a square pyramid to determine which shape is a rectangular box and which one is a square pyramid.
