Question

25 points! (3) MEANS CUBE Find the length of a cuboid whose volume is 150cm(3), breadth is 3cm and height is 5cm.

Answer 1

Volume of cuboid = 150cm³

=> l x b x h = 150

=> l x 3 x 5 = 150

=> l x 15 = 150

=> l = 150/15

=> l = 10

Hence, Length of cuboid = 10cm.

Answer 2

${\red{\underline{\underline{\bold{Given:-}}}}}$

• Volume of cube = $150{cm}^{3}$
• Breadth of cube = 3cm
• Height of cube = 5cm

${\blue{\underline{\underline{\bold{To\:Find:-}}}}}$

• The length of the cube

${\green{\underline{\underline{\bold{Solution:-}}}}}$

Length of cuboid =

$\frac{volume}{breadth \times height} \\ \\ = \frac{150}{3 \times 5} \\ \\ = \frac{150}{15} = 10cm$

Therefore the length of cuboid = 10cm

______________

Formula used:-

• Length = $\frac{Volume}{breadth \times height}$

_________________

Additional Information:-

• Volume of cuboid = Length×breadth×height

• Breadth = $\frac{Volume}{heigth \times length}$

• Height = $\frac{Volume}{length \times breadth}$
