Question

A rectangular tank has square base of side 25cm and height 20 cm.find its capacity in litres​

Answer 1

Answer:

12.5 litres

Step-by-step explanation:

Side of square base = 25 cm

Area of base = (25)² = 625 cm²

Height = 20 cm

Volume of tank = (625×20) cm³ = 12500 cm³

12500 cm³ = 12.5 litres

Answer 2

$\large\underline{\sf{Solution-}}$

Given that

• A rectangular tank has square base of side 25cm and height 20 cm.

It implies

$\: \: \: \: \: \: \: \: \bull \: \sf \: \: Length_{(tank)} = 25 \: cm$

$\: \: \: \: \: \: \: \: \bull \: \sf \: \: Breadth_{(tank)} = 25 \: cm$

$\: \: \: \: \: \: \: \: \bull \: \sf \: \: Height_{(tank)} = 20 \: cm$

Now, we have to find capacity of the tank, that means we have to find the volume of tank.

We know,

$\boxed{ \sf \: Volume_{(tank)} =Length_{(tank)} \times Breadth_{(tank)} \times Height_{(tank)} }$

On substituting the values, we get

$\rm :\longmapsto\:Volume_{(tank)} = 25 \times 25 \times 20$

$\rm :\longmapsto\:Volume_{(tank)} = 12500 \: {cm}^{3}$

$\rm :\longmapsto\:Volume_{(tank)} = \dfrac{12500}{1000} \: litres$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{ \red{ \sf \: \because \: 1 \: litre \: = \: 1000 \: {cm}^{3} }}$

$\bf\implies \:Volume_{(tank)} = 12.5 \: litres$

Cube: 

• A cube has six faces, eight vertices and twelve edges. All the faces of the cube are in square shape and have equal length.

Cuboid: 

• A cuboid has six faces, eight vertices and twelve edges. The faces of the cuboid are parallel. But not all the faces of a cuboid are equal in dimensions.

Formula's of Cube :-

• Total Surface Area = 6(side)²

• Curved Surface Area = 4(side)²

• Volume of Cube = (side)³

• Diagonal of a cube = √3(side)

• Perimeter of cube = 12 x side

Formula's of Cuboid

• Total Surface area = 2 (Length x Breadth + breadth x height + Length x height)

• Curved Surface area = 2 height(length + breadth)

• Volume of the cuboid = (length × breadth × height)

• Diagonal of the cuboid =√(l² + b² + h²)

• Perimeter of cuboid = 4 (length + breadth + height)
