Question

Find the area of the cross-section, assuming it to be uniform, of a solid, given that its volume is 92.8 cm³ and length is 6.4 m.

Answer 1

Given: Volume = 92.8 cm³, Length = 6.4 m.

Step-wise calculation:

1. Convert length to centimetres:

6.4 m = 6.4 × 100 cm 

= 640 cm

2. Area of uniform cross-section

= `"Volume"/"Length"`

= 92.8 cm³ ÷ 640 cm

= 0.145 cm²

Area of the cross-section = 0.145 cm² (which is 1.45 × 10^–5 m²).
