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
