How many square centimetres are there in the surface area of a solid cube of side 1 metre?

60,000 cm^2.

Step-by-step explanation:

1 metre = 100 centimetres.

Area of one side of the cube = 1*1 metre = 100*100

= 10,000 cm^2.

Now there are 6 sides on a cube so the total surface area

= 6 * 10,000 = 60,000 cm^2

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
