Question
What is the maximal number of spherical balls of radius
1 cm each that can be placed inside a cubical box of height 10 cm?Solution
Diameter of each ball = 2 Γ 1 = 2 cm Number of balls arranged with respect to the length of box = 10/2 = 5 Number of balls arranged with respect to the breadth of box = 10/2 = 5 Number of balls arranged with respect to the height of box = 10/2 = 5 β΄ Required number of balls = 5 Γ 5 Γ 5 = 125
20.06% of 359.89 - 15.95 X ? + 18.07 X 14.95 = 48.87 X 6.02
28.95% of 924.78 + 1955% of 38.99 = ?
? + 151.99 β 100.01 = 23.01 Γ 4.98
(β1157 + 10.15% of 159.89) Γ 4.85 + 150.25 = ? Γ 19.67
233.98 + 73 Γ β35.95 - ? = 275.94 Γ· 3.99
[15.87% of 599.97 + 40.08 Γ ?] Γ· 4.04 = 8.082.02
37.06% of 783.45 + 2125% of 51.89 = ?
