Question

all the formulas of volume surface area of 3d figure.​

Answer 1

Step-by-step explanation:

the volume of cube=side^3

the surface area of cube=6a^2

the volume of cuboid=(l*b*h)

the surface area of cuboid=2{lb+bh+lh}

I hope it will be helpful

Answer 2

Step-by-step explanation:

cuboid:

T.S.A=2(LB+BH+HL)

C.S.A=2(L+B)H

VOLUME=LBH

CUBE:

T.S.A=6a^2

C.S.A=4a^2

VOLUME=L^3

CYLINDER:

T.S.A=2πr(h+r)

C.S.A=2πrh

VOLUME=πr^2h

SPHERE:

T.S.A=4πr^2

VOLUME=4/3πr^3

HEMISPHERE:

T.S.A=3πr^2

C.S.A=2πr^2

VOLUME=2/3πr^3

CONE:

T.S.A=πr(l+r)

C.S.A=πrl

VOLUME=1/3πr^h

FRUSTUM OF A CONE:

T.S.A=π[R^2+r^2+l(R+r)]

C.S.A=πl(R+r)

VOLUME=1/3πh(R^2+Rr+r^2)
