Question

LSA, TSA, volume of cuboid, cube, cylinder, cone, hemisphere​

Answer 1

Answer:

volume of cuboid=l×b×h

TSA of cuboid=2(lb +bh+hl)

LSA of cuboid=2(l+b) ×h

LSA of cube=4a²

TSA of cube=6a²

volume of cube=a³

volume of cylinder=πr²h

LSA of cylinder=2πrh

TSA of cylinder=2πr(h+r)

volume of cone =1/3πr²h

TSA of cone=πr(l+r)

CSA of cone =πrl

volume of hemisphere=2/3πr³

CSA of hemisphere=2π²

TSA of hemisphere=3πr²

Answer 2

$\huge{\underline{\underline{\mathtt{\red{Some\:important\:formulae}}}}}$

★ Lateral surface area ★

• Cuboid = 2(length+breadth)×height
• Cube = 4×a

where "a" is side of cube

• Cylinder = 2πrh
• Cone = πrl
• Hemisphere = 2πr²

★ Total surface area ★

• Cuboid = 2(lb+bh+lh)
• Cube = 6a²
• Cylinder = 2πrh+2πr²
• Cone = πrl + πr²
• Hemisphere = 3πr²

★ Volume ★

• Cuboid = length × breadth × height
• Cube = a³
• Cylinder = πr²h
• Cone = 1/3πr²h
• Hemisphere = 2/3πr³
