Question

If a cuboid has length = 3cm breadth = 1cm and height = 2cm, its volume will be ...

Answer 1

Answer:

volume of cuboid = l×b×h

= 3cm×1cm×2cm

= 6cm³

Answer 2

Given :-

• Length (l) = 3cm
• Breadth (b) = 1cm
• Height (h) = 2cm

To Find :-

• Volume of a cuboid ?

Solution :-

◆ We know that,

Volume of a cuboid = (length × breadth × height)

Now, substitute the values :-

↦ Volume of a cuboid = ( 3 × 1 × 2 )cm

↦ Volume of a cuboid = 6 cm³

■ Hence, volume of a cuboid is 6 cm³.

Formula to be remembered :-

Ⅰ) Curved Surface Area (CSA) of cuboid = 2(l+b)h

Ⅱ) Total Surface Area (TSA) of cuboid = 2(lb+bh+hl)

Ⅲ) Volume of cuboid = length × breadth × height

Ⅳ) Curved Surface Area (CSA) of cube = 4a²

Ⅴ) Total Surface Area (TSA) of cube ‌= 6a²

Ⅵ) Volume of cube = a³

Ⅶ) Curved Surface Area (CSA) of cylinder = 2πrh

Ⅷ) Total Surface Area (TSA) of cylinder = 2πr(h+r)

Ⅸ) Volume of cylinder = πr²h

Ⅹ) Curved Surface Area (CSA) of cone = πrl

Ⅺ) Total Surface Area (TSA) of cone = πr(l+r)

Ⅻ) Volume of cylinder = 1/3πr²h
