Guidance for Solving Exercise 3 Pages 122-123 Math Textbook Grade 5
Problem Statement:
A rectangular box has length 8cm, width 7cm, and height 9cm. A cube has a side length equal to the average of the three dimensions of the rectangular box. Calculate:
a) Volume of the rectangular box
b) Volume of the cube
Solution Method:
- Formula for calculating the volume of a rectangular box: V = a x b x c (Volume equals the product of length, width, and height)
- Formula for calculating the volume of a cube: V = a x a x a (Volume equals side length cubed)
Answers:
a) Volume of the rectangular box is:
8 x 7 x 9 = 504 (cm3)
b) Length of the cube's side:
(8 + 7 + 9) : 3 = 8 (cm)
So, the volume of the cube is:
8 x 8 x 8 = 512 (cm3)
Answer: a) 504cm3 and b) 512cm3
