Question

A cuboidal block of silver is 9 cm long, 4 cm broad and 3.5 cm in height. From it, beads
of volume 1.5 cm" each are to be made. Find the number of beads that can be made
from the block​

Answer 1

Answer:

Step-by-step explanation:

Given :-

Dimensions of cuboidal block of silver :-

Length = 9 cm

Breadth = 4 cm

Height = 3.5 cm

Volume of beads made = 1.5 cm³

To Find :-

Number of beads.

Solution :-

⇒ Number of beads = 9 × 4 × 3.5/1.5

⇒ Number of beads = 126/1.5

⇒ Number of beads = 84

Hence, 84 beads can be made  from the block​.

Answer 2

$\large\red{\sf\underline{\underline{\:Given:\:\:}}}$

Dimensions of Cuboidal block :-----------

• Length = 9cm
• Breadth = 4cm
• Height = 3.5cm

$\underline{{\colorbox{yellow}{Question:-}}}$ we have to Find number of beads that can be made from the block with each Volume as 1.5cm³ .

$\underline{{\colorbox{cyan}{Answer}}}$

we know that Volume of cuboid with length as l , breadth as b , and height as h is ===

$\large\red{\boxed{\sf</strong><strong> </strong><strong>v = l \times b \times h</strong><strong>}}$

Putting values we get,

$v = l \times b \times h \\ \\ v = 9 \times 4 \times 3.5 \\ \\ v = 126cm^{3}$

Now, Let N number of beads will be made from this cuboidal box .

So,

Volume of Both will be Equal ...

Volume of Each bead is given = 1.5cm³

Volume of N beads will be = (N × 1.5)cm³

Therefore,

$126 = (N \times 1.5) \\ \\ N = \frac{ \cancel126}{ \cancel1.5} \\ \\ N = 84$

So, 84 beads can be made From the box .....
