Question

Volume of a rectangular tank with length 30 cm breadth 20 cm and height 10 cm

Answer 1

volume = length x width x height

volume = 30 x 20 x 10

volume = 6000 cm³

Find the volume of rectangular tank with length 30 cm breadth 20 cm and height 10 cm.

$\huge\underline\mathbb{\red S\pink{O}\purple{LU} \blue{T} \orange{IO}\green{N :}}$

★ Given that,

$\bf\: ↪ Length_{ (Rectangle) }= 30 cm.$

$\bf\: ↪ Breadth_{ (Rectangle) }= 20 cm.$

$\bf\: ↪ Height_{ (Rectangle) }= 10 cm.$

$\bf\: ➡ Volume\:of\:rectangle\: = lbh$

• Substitute the values.

$\bf\: ⟹ 30 \times 20 \times 10$

$\bf\: ⟹ 6000$

$\underline{\boxed{\bf{\purple{∴ Volume\:of\:rectangular\:tank\:is\:6000\:cm^{3}.}}}}$

★ Important formulae :

$\sf\: ◼ \: Total\:surface\:area\:of\:rectangle\:= 2[lb + bh + lh ]$

$\sf\: ◼ \: Lateral\:surface\:area\:of\:rectangle\:= 2h[l + b]$

$\sf\: ◼ \: Volume\:of\:rectangle\:= lbh$
