Question

can i plz get all the formulas for surface areas and volumes of cube , cuboid , cylinder , cone , sphere and hemisphere !!..........in tsa and lsa

Answer 1

Cube =TSA - 6×side×side
LSA - 4×side×side
Cuboid =TSA - 2(lb+bh+hl)
LSA - 2h(l+b)
l=length,b=breath,h=height

Cylinder = TSA - 2×pi×radius(radius+height)
LSA - 2×pi×radius×height

Cone =TSA - pi×radius(radius+slant height)
LSA - pi×radius×slant height

Sphere =TSA - 4×pi×radius×radius
LSA - 4×pi×radius×radius

Hemisphere = TSA - 3×pi×radius×radius
LSA - 2×pi×radius×radius

Answer 2

area of cube is a*a (here a is side of cube. and volume is a*a*a.. cuboid surface are is = 2(lb*bh*lh) where l is length , b is breath , h is hight. area of cylinder = 2*pai*r(r+h) where r is radius and h is hight. volume = pai *r*r*h where r is radius and h is hight. volum of cone = 1/3*pai*r*r*h. area of cone =pai* r(r+ spare root of(h*h+r*r). area of sphere =4*pai*r*r.. volume of sphere= 4/3* pai*r*r*r*. volume of hemisphere= 2/3* pai*r*r*r. area of hemisphere =2*pai*r*r. .... note :- all area formulas are surface area formulas
