Mensuration

Question 1

tsa,Lsa,V,Bd of a cuboid

Answer 1

TSA=2(LB+BH+HL)
LSA=2H(L+B)
VOILUME=LBH
BODY DIAGONAL=ROOT L^2+B^2
+H^2

Question 2

area ,volume,body diagonal,lsa cube

Answer 2

A=6a^2

V=a^3,

body diagonal=xroot3
lsa=4a^2

Question 3

Volume,area sphere

Answer 3

Tsa=4πr^2

v=4⁄3πr^3

Question 4

volume,tsa,lsa hemisphere

Answer 4

tsa=3πr^2
V=2⁄3πr^3
Lsa=2πr^2

Question 5

Fustum of a cone lsa,tsa.v

Answer 5

Tsa=π(R^2 + r^2 + Rl + rl)
v=⅓πh(R^2+Rr+r^2)
Lsa=πl(R + r)where,l=√(R-r)2+h

Question 6

lsa,v,tsa of cone

Answer 6

Lsa=πrl

tsa=πr(l+r)

v=⅓πr^2h
