Question

curved surface area, Total surface area and volume of the following shapes
1. cube
2. cuboid
3. cylinder
4. cone
5. sphere
6. hemisphere​

Answer 1

cube=

lsa=4 a sq

tsa=6 a sq

volume =a cube

Answer 2

Answer:

curved surface area of cube = 4 a^

curved surface area of the cuboid = 2(lb+bh+hl) - l× b

curved surface area of the cylinder = 2πrh

curved surface area of cone = πrl

curved surface area of hemisphere = 2πr^

total surface area of cube = 6a^

total surface area of the cuboid = 2(lb+bh+hl)

total surface area of the cylinder = 2πh + πr^

total surface area of the cone = πr(r+l)

total surface area of the sphere = 4πr^

total surface area of hemisphere = 3πr^

volume of the cube = a cube

volume of the cuboid = l×b×h

volume of the cylinder = πr^h

volume of the cone = =πr2h3

volume of the sphere = 4/3πr3

volume of hemisphere = 2/3πr3
