Answer 1

Answer:

Step-by-step explanation:

Let's first draw a line segment of length 7.3 cmWe follow these steps1. ... Since length is 7.3 cm, we measure 7.3 cm using ruler and compass 3. ... We keep pointed end at point A, and draw an arc on line l So, the required line ... we need to find its axis of symmetry That is, we need to make its perpendicular

Answer 2

☆ Solution ☆

Given :-

• A solid metal block is 25 cm long, 15 cm wide and 10 cm high. It is cut into solid cubical blocks of the same size.

To Find :-

• The number of cubical blocks, if each side measures 5 cm.

Step-by-Step-Explaination :-

As we know that :-

Volume of cuboid = length × breadth × height

Putting the respective value,

Volume of cuboid = 25 × 15 × 10

Volume of cuboid = 3750 cm³

Now,

As we know that :-

Volume of cube = ( side )³

Putting the respective value,

Volume of cube = ( 5 )³

Volume of cube = 125 cm²

Now,

Let the number of cubical box be x

So,

Volume of cuboid = x × Volume of cube

Putting the respective value,

=> 3750 = x × 125

=> 125x = 3750

=> x = 3750/125

=> x = 30

Hence,

The number of cubical block = 30
