Answer 1

Q: Match the following:

1. Surface area of a cube = 6a²
2. Surface area of a cuboid = 2(lb + bh + hl)
3. Surface area of a cylinder = 2πr(r + h)
4. Volume of a cube = a³
5. Volume of a of a cylinder = πr²h

More formulae:

Cube:→

1. Volume of a cube = a³ cubic unit
2. Total surface area of a cube = 6a² sq. unit
3. Curved/Lateral surface area of cube = 4a² sq. unit

Cuboid:→

1. Volume of a cuboid = lbh cubic unit
2. Total surface area of a cuboid = 2(lb + bh + hl) sq. unit
3. Curved/Lateral surface area of cuboid = 2h(l+ b) sq. unit

Cylinder:→

1. Volume of a cylinder = πr²h cubic unit
2. Total surface area of a cylinder = 2πr(r + h) sq. unit
3. Curved/Lateral surface area of cylinder = 2πrh sq. unit

Abbreviations used:

• Edge of square is denoted by a.
• Length is denoted by l.
• Breadth is denoted by b.
• Height is denoted by h.
• Radius of bottom and top of cylinder is denoted by r.

Answer 2

Answer:

Required Answer :-

1) Surface area of cube = 6a²

2) Surface area of cuboid = 2(lb + bh + lh)

3) Surface area of Cylinder = 2πr(r + h)

4) Volume of cube = E³

5) Volume of Cylinder = πr²h

Know More :-

Here, we used some abbreviation let's see the meaning of each

1. a = edge or side of cube
2. L = Length, B = Breadth, H = Height
3. π = 22/7 or 3.14, R = Radius, H = Height
4. E = Edge
5. π = 22/7 or 3.14, R = Radius, H = Height
