Mensuration , volume and surface area of solid figures - Cube, cuboid, cylinder cone, sphere and hemisphere. Draw a well labelled diagram and write formula of each
Answers
Given : Cube, cuboid, cylinder cone, sphere and hemisphere.
To find : Write formula for Volume and surface area of each
Solution:
Solid figure Volume Surface Area
Cube Side³ 6 * Side²
Cuboid L*B*H 2(LB + BH + LH)
L , B & H are Length Breadth & height of Cuboid
Cylinder π(r)²h 2πrh + 2πr²
r = radius of cylinder & h = height of cylinder
Cone (1/3) π(r)²h πr² + πr√(r² + h²)
r = radius of cone & h = height of cone √(r² + h²) = slant height
Sphere (4/3)πr³ 4πr²
r = radius of Sphere
HemiSphere (2/3)πr³ 2πr²
r = radius of Hemi Sphere
