What Have We Discussed?

SurfaceVolume area of a solid is the sum of the areas of its faces.

Surface area of

cuboid = 2(lb + bh + hl)

cube = 6a2

cylinder = 2πr(r + h)

Amount of region occupied by a solid is called its volumesurface.

Volume of:

cuboid = l × b × h

cube = l3

cylinder = πr2h

Capacity units:

1 cm3 = 1 (Write short-hand unit)

1 L = cm3

1 m3 = 1000000 cm3 = L
