Question

.An ice slab has dimensions 75 cm × 60 cm×30 cm. If density of ice be 910 kg/meter cube then Calculate the mass of ice slab. Express your answer in kg also.

pls tell it's urgent.​

Answer 1

$\Large{\underline{\underline{\bold{☆Given:}}}}$

• Dimensions of an ice slab = 75cm×60cm×30cm.
• Density of ice slab = 910 kg/meter³

$\Large{\underline{\underline{\red{\bold{➸To\;Find:}}}}}$

• Mass of the ice slab in kgs.

$\Large{\underline{\underline{\bold{\color{salmon}๛Required\; Response:}}}}$

Volume of ice slab

$75cm \times 60cm \times 30cm \\ (75 \times 60 \times 30) {cm}^{3} \\ 135000 {cm}^{3}$

• Volume = 135000cm³

We know that

• $\pink{\bf{Density(\rho) = \frac{Mass(m)}{Volume(v)}}}$
• $\pink{\bf{Mass = Density×Volume}}$

Mass of the ice block

• 1000 cm³ = 0.001m³

$135000cm³ \times 910kg/m³ \\ 135 \times 1000 {cm}^{3} \times 910 \\ 135 \times 0.001\cancel{m³} \times 910kg/\cancel{m³} \\→\; 122.85kg$

Mass of the ice slab ☞ $\Large\boxed{\blue{\bold{122.85kg}}}$
