A cubical box is 75cm high. how many rectangular packets each of 25×15×5cm are required to fill the box.

Explain:

please help

225 packets

Step-by-step explanation:

Height of cubical box = 75cm

Dimension of rectangular packet = 25×15×5cm

Volume of cubical box = 75^3

Volume of cubical box = (75 * 75 * 75)cm³ = 421,875 cm³

Volume of rectangular packet = 25×15×5cm = 1875 cm³

Number of rectangular packets required /

421,875 cm³ / 1875 cm³

= 225

Number of packets required = 225 packets

48.125 ft³

Step-by-step explanation:

The space occupied by the new generator is the product of it's dimension:

The space occupied = Length * width * height

Space occupied = 3 1/2 * 5 1/2 * 2 1/2

Space occupied = 7/2 * 11/2 * 5/2

Space occupied = (7*11*5) / (2*2*2) = 385 / 8

Space occupied = 48.125 ft³
