explain step by step​ plz it's urgent​

Answer 1

Answer:

121.635 kg

Step-by-step explanation:

Given:

• An ice slab has dimensions 75 cm × 60 cm × 30 cm.
• Density of ice = 901 kg/m³

To find:

• The mass of ice slab in kg.

Solution:

First we will find the volume of ice slab using formula.

• Volume = l × b × h

Here,

• l is the length of a ice slab.
• b is the breadth of a ice slab.
• h is the height of a ice slab.

Putting the values in the formula, we have:

• Volume of a ice slab = 75 × 60 × 30
• Volume of a ice slab = 4500 × 30
• Volume of a ice slab = 135000 cm³

Converting it into m³

• 1 cm = 1/100 m
• 1 cm³ = 1/(100 × 100 × 100) m³

• Volume of a ice slab = 135000/1000000
• Volume of a ice slab = 135/000
• Volume of a ice slab = 0.135 m³

Now, the mass of ice slab by using formula,

• Mass = Density × Volume
• Mass = 901 × 0.135
• Mass = 121.635 kg

∴ The mass of ice slab = 121.635 kg
