Question

find the length of a cuboid whose volume 315 cm³ and whose breath and height are 3 cm each.​

Answer 1

$volume \:of \: cube \: = l \: \times b \: \times \: h \: \\ 315 = l \: \times 3 \: \times 3 \\ 315 = l \ \times 9\: \: \\ \frac{315}{9} = l \: \\ l = 35 \: cm \:$

lenght of cuboid = 35 cm

Answer 2

$\huge{\underline{\bf{GivEn:}}}$

• volume of cuboid = 315cm³
• Height of cuboid = 3cm
• Breadth of cuboid = 3cm

$\huge{\underline{\bf{ To ~finD:}}}$

• Length of cuboid.

$\huge{\underline{\bf{Solution:}}}$

Here, we have given volume, Breadth and Height are 315cm³, 3cm and 3cm respectively. Let suppose that length of cuboid is L.

We know that :

Volume of cuboid = Length× Breadth × height

In which ,

• Volume = 315cm³ ••••( given)
• Breadth = 3cm ••••( given)
• Height = 3cm •••••(given)

Let put known values in this formula :-

Volume of cuboid = Length× Breadth×height

=> 315 = L × 3×3

=> 315 = L × 9

=> L = $\large{\sf{ \frac{315}{9} }}$

=> L = 35cm

Hence,

$\large{\boxed{\sf{\green{Length~of\: cuboid\: is\: 35cm}}}}$
