NCERT Revision Notes for Chapter 13 Surface Areas and Volumes Class 10 Maths
CBSE NCERT Revision Notes1
Cuboid
Answer
l=length, b= breadth, h=height
Curved/lateral Surface Area = 2h(l +b)
Surface Area = (lb+bh+lh)
Volume = lbh
2
Cube
Answer
Side =a
Curved/lateral surface area = 4a2
Total Surface Area = 6a2
Volume = a3
3
Cylinder
Answer
r = Radius of Cylinder
h = Height of Cylinder
Curved Surface Area = 2πrh
Total Surface Area = 2πrh +2 πr2
Volume = πr2 h
4
Cone
Answer
h= height of cone
r = radius of cone
l = slant height of cone = (h2+r2)
Curved Surface Area = πrl
Total Surface Area = πrl + πr2h
5
Sphere
Answer
r= radius
Surface Area = 4 πr2
6
Hemi-Sphere
Answer
Curved Surface Area = πr2
Total Surface Area = 2πr2
7
Frustum
Answer
