Question

Yukiko has 10,000 cubic centimeters of sand in a bag.She turns the pyramid shown upside down and pours the sand into it .Wjat fraction of the pyramid can she fill with her bag of sand? when you have 60 cm deep and 40 cm wide by 30 cm length

Answer 1

She can fill 5/12 of the pyramid.

The volume of a pyramid is given by the formula 
V = 1/3lwh.  Using our information, we have:

V = 1/3(40)(30)(60) = 24000 cm³

She has 10,000 cm³ of sand; 10000/24000 = 5/12.
