Work out the surface area of the cube. If l, b and h denote respectively the length, breadth and height of a cuboid, then (i) total surface area of the cuboid = 2(lb + bh + lh) square units A cube has a volume of 1000cm3.

Four times the area of a curved surface area of a cylinder is equal to the six times the sum of the area of its base. If the height is 12cm , find its curved surface area. Hence, the lateral surface area of a cuboid (l.s.a.) = (l × h).
This gives, tsa of new solid = csa of one hemisphere + csa of cylinder +.
So, the total surface area of the new solid is the sum of the curved surface areas of each of the individual parts. Jamie is trying to work out the surface area of the cuboid below. Develop and apply formulae to calculate surface area of a cube and a cuboid demonstrate an understanding of the volume of a cube and a cuboid develop and apply formulae to determine. Can you spot any mistakes?
For example, the total area of all the four walls of the cuboidal room in which you are sitting is the lateral surface area of the room. The document provides examples calculating the surface. By finding the areas of these known shapes we can find out the required area of the unknown figure. Areas of complex figures can be broken down and analysed as simpler known shapes.
Find the ratio of (i) their curved surface;
3 cm and height 4 cm is equal to the entire surface of a solid right circular cylinder of diameter 4 cm.
