Question

A block of wood has dimensions 4cm, 5cm and 20cm . Find The volume of the wood​

Answer 1

Wood is a cuboid

• Length=L=4cm
• Breadth=5cm
• Height=H=20cm

We know

$\boxed{\sf Volume=LBH}$

$\\ \sf\longmapsto Volume=4\times 5\times 20$

$\\ \sf\longmapsto Volume=20\times 20$

$\\ \sf\longmapsto Volume=400cm^3$

Answer 2

Answer:

400 cm³

Explanation:

$\Large{\underline{\underline{\mathfrak{Given:-}}}}</p><p>$

Dimensions of the bock:-

• length= 4 cm
• breadth= 5 cm
• height= 20 cm

$\Large{\underline{\underline{\mathfrak{To\:Find:-}}}}$

• Volume= ?

$\Large{\underline{\underline{\mathfrak{Concepts:-}}}}$

The block of wood is simply a Cuboid

$\large{\boxed{\mathsf{Volume_{Cuboid}=l×b×h}}}$

$\Large{\underline{\underline{\mathfrak{Solution:-}}}}$

Put the value of l , b and h:-

$\large{\mapsto 4×5×20}$

$\large{ \mapsto 20×20}$

$\large{ \mapsto 400 \: cm³}$

$\Large{\underline{\underline{\mathfrak{Useful\: Formulae:-}}}}$

• Total Surface Area of a Cuboid= 2(lb+bh+hl)
• Curved Surface Area of a Cuboid= 2(l+b)×h
• Diagonal of a Cuboid= √(l²+b²+h²)
