Answer:
(a) 13 824cm³
(b) 452.16cm³
(c) 13 371.84cm³
Step-by-step explanation:
Formulas (For easier reference):
Volume of cubic box = length³
Volume of ball = × radius²
Radius =
We just have to put in the formulas.
Volume of box = 24³
= 13 824cm³
Volume of ball = 3.14 × ()²
= 3.14 × 144
= 452.16cm³
Remaining space = 13 824cm³ - 452.16cm³
= 13 371.84cm³
Thickness of 1 quarter = 1.75 mm
So, 1000 quarters will be =
= 1750 mm
So, a stack of 1000 quarters will be 1750 mm high.
