C. A rectangular aluminium block with a cavity at its center is completely submerged in water as shown in Figure 2.3. The dimensions of the block are 10 cm x 8 cm x 6 cm. The densities of aluminum and water are 2700 kg m³ and 1000 kg m³ respectively. The mass of air in the cavity can be neglected. (10 Marks) aluminium block submerged in water of density 1000 kg m³ water 6 cm cavity at the block's centre 8 cm 10 cm Figure 2.3 a. The block is able to stay at rest uprightly in water as shown in Figure 3.3. Draw and label the force(s) acting on the aluminium block in Figure 2.3 b. Deduce the weight of the aluminium block using the pressure difference found in (b)(i). Hence, find the volume of the cavity.
