Question a
The given cube has length,
[tex]l = 5cm[/tex]
If the cube us enlarged by a scale factor of 2, then the enlarged cube has length,
[tex]L=2 \times 5cm = 10cm[/tex]
Question b.
The volume of the original cube is
[tex]v = {5}^{3} = 125 {cm}^{3} [/tex]
To find the volume of the enlarged cube, multiply the volume of the original cube by 2³.
The volume of the enlarged cube is
[tex]V = {2}^{3} \times 125 = 1000 {cm}^{3} [/tex]
Question C
The surface area of the original cube is
[tex]s.a = 6 {l}^{2} [/tex]
[tex]s.a = 6 \times {5}^{2} = 150 {cm}^{2} [/tex]
To find the surface area of the enlarged cube multiply the surface area of the original cube by 2².
[tex]S. A = {2}^{2} \times 150 = 600 {cm}^{2} [/tex]
