(i) No, ~150 pages cover roughly 7.5 m², whereas a standard classroom floor is around 40 to 50 m². (ii) Storeroom volume is 9,000 cu ft (~255 m³); dividing by textbook volume (~0.0006 m³) fits roughly 350,000 to 400,000 books. Cbse ...
(i) A dough ball of radius 6 cm yields (6/1.5)³ = 64 small dough balls of radius 1.5 cm, producing about 64 chapatis. (ii) Edible volume is the hemispherical shell volume: (2/3)π(R³ − r³) using outer and inner radii. Class 9 ...
A standard refill tube is a cylinder of internal radius about 0.1 cm and ink length 10 cm. The ink volume is πr²h ≈ 3.14 × (0.1)² × 10 ≈ 0.314 cm³ (or ~0.3 mL). Ganita Manjari Part 2 Class 9 ...
The water must rise by 20 − 16 = 4 cm. Required rise volume is π(4²)(4) = 64π cm³. Each spherical marble has volume (4/3)π(1³) = (4/3)π cm³. Dividing 64π by (4/3)π gives exactly 48 marbles. Ganita Manjari Part 2 Class ...
