(i) 4cm × 7cm, (ii) 7cm × 10cm
(iii) 4cm × 10cm.


If the density of iron is is nearly 8g cm-³ and g = 10m/s² , find the minimum and maximum pressure as calculated by Rohan.​

Answer 1

Answer:

Rohan placed an iron cuboid of dimensions 4 cm × 7 cm × 10 cm on a tray containing fine sand. He placed the cuboid in such a way that it was made to lie on the sand with its faces of dimensions (1) 4 cm × 7 cm (2) 7 cm × 10 cm (3) 4 cm × 10 cm. If the density of iron is nearly 8g/cm3 and g = 10 m/s2, find the minimum and maximum pressure as calculated by Rohan.
