Answer 1

Step-by-step explanation:

2) (a) Volume of cube = a³

= 3³ = 27 cm³

(b) Volume of cuboid = length * breadth * height

= 5 * 5 * 5

= 125 cm³

3) Volume of rectangular box = Length*Breadth*Height

= 20*10*5

= 1000cm³

4) Volume of cube = a³

= 7³ = 343cm³

Answer 2

Answer:

Your answer is here

Step-by-step explanation:

2. a) volume of cube = a^3

                                = 3 x 3 x 3

                                = 27 cm^3

 b) volume of cube = a^3

                               = 5^3

                               = 125c m^3

3. volume of cuboid = 2(lb+bh+hl)

                                = 2( 20x10+10x5+5x20)

                                = 2(200+50+100)

                                = 2(350)

                               = 700 cm^3

4. volume of cube = a^3

                              = 7^3

                              = 343 cm^3

       Hope it helps you.
