I need this ASAP will give brainliest Question 2

Answer 1

Answer:

2a. 24 m³

2b. 19200 Kg

2c. 192000 N

2d. 16000 N/m²

Explanation:

2a. Determination of the volume of paraffin.

Length (L) = 4 m

Width (W) = 3 m

Height (H) = 2 m

Volume (V) =?

V = L × W × H

V = 4 × 3 × 2

V = 24 m³

Therefore the volume of paraffin is 24 m³

2b. Determination of the mass of paraffin.

Volume (V) = 24 m³

Density (ρ) = 800 Kg/m³

Mass (m) =?

ρ = m / V

800 = m / 24

Cross multiply

m = 800 × 24

m = 19200 Kg

Therefore, the mass of paraffin is 19200 Kg

2c. Determination of the weight of paraffin.

Mass (m) = 19200 Kg

Acceleration due to gravity (g) = 10 N/Kg

Weight (W) =?

W = m × g

W = 19200 × 10

W = 192000 N

Therefore, the weight of paraffin is 192000 N

2d. Determination of the pressure.

Density (ρ) = 800 Kg/m³

Depth (h) = 2 m

Acceleration due to gravity (g) = 10 N/Kg

Pressure (P) =?

P = ρgh

P = 800 × 10 × 2

P = 16000 N/m²
