➷ A) 5 x 2 = 10

The enlarged cube's side length is 10 cm

B) Work out the volume of the original cube:

Volume = 5 x 5 x 5

Volume = 125 cm^3

As it is volume, you have to cube the scale factor

2^3 = 8

Multiply this new scale factor by the volume:

125 x 8 = 1000

The enlarged cube's volume is 1000 cm^3

C) Work out the surface area of the original cube:

S.A = 5 x 5 x 6

S.A = 150 cm^2

As it is area, you have to square the scale factor

2^2 = 4

Multiply this new scale factor by the surface area:

150 x 4 = 600

The enlarged cube's surface area is 600 cm^2

Planet earth has a mass of 5.9726x10²⁴ kg.then: 5.9726x10²⁴ kg=100% of the total earth mass.if the water´s mass=5x10-4 % of the total mass, we can solve this problem by the rule of three.5.9726x10²⁴ %*10⁻⁴ %x=(5.9726x10²³ kg)(5*10⁻⁴  %) / 100 %=2.9863x10¹⁹ kganswer:   the mass of the planet´s water would be   2.9863 x 10¹⁹ kg.
