Question

pleas tell me whole ​

Answer 1

Volume Of Cuboid = 24000 cm³

Step-by-step explanation:

GIVEN

Length = 40 cm

Breadth = 30 cm

Height = 20 cm

___________________________

TO FIND

Volume Of Cuboid

___________________________

FORMULAS

Total Surface Area Of Cuboid = 2 × [ ( Length × Breadth ) + ( Breadth × Height ) + ( Height × Length ) ]

Perimeter Of Cuboid = 4 × ( Length + Breadth + Height )

Volume Of Cuboid = Length × Breadth × Height

Diagonal Of Cuboid = √ ( Length² + Breadth² + Height² )

___________________________

We know that,

Volume Of Cuboid = Length × Breadth × Height

Volume Of Cuboid = 40 × 30 × 20

Volume Of Cuboid = 24000

Volume Of Cuboid = 24000 cm³

Answer 2

$\huge \sf \underline \red{Answer : }$

$\sf \underline \purple{ \therefore \: Volume \: of \: cuboid = 24000 \: {cm}^{2}}$

$\sf \underline{option(a)}$

$\huge \sf \underline \pink{To \: find : }$

• Volume of cuboid (box)

$\huge \sf \underline \blue{Solution : }$

$\sf {Given}\begin{cases}&\sf{Length = \sf{40cm}} \\ \\ &\sf{breadth = \sf{30cm}} \\ \\ &\sf{height = \sf{20cm}}\end{cases}$

$\sf \underline{we \: know \: that : }$

$\sf{ \boxed{ \underline{ \underline{ \red{ \tt{Volume \: of \: cuboid = l \times b \times h\: }}}}}}$

• length = 40cm

• breadth = 30cm

• height = 20cm

$\: \: \: \: \: \: \: \: \: \sf \implies{40 \times 30 \times 20}$

$\: \: \: \: \: \: \: \: \: \sf \implies{24000}$

$\: \: \: \: \: \: \: \: \: \sf \implies{24000 \: {cm}^{2} }$

$\sf \underline{ \therefore \: Volume \: of \: cuboid = 24000 \: {cm}^{2}}$
