A toy shop receives , a delivery of 400 colourful foam pyramids. The foam has a density of 0.2g/cm^3 Each pyramid has a base of area 64cm^2 and a height of 11cm. What is the total I mass of the pyramids? Give your answer in grams to 3 s.f.

This is a problem concerned with the relationship between density, mass, and volume in Physics. The problem states that the density is and that each pyramid has a base of with a height of . The étage is essentially figuring out the volume, then the mass of one pyramid and multiply by the number of total pyramids. The volume of a pyramid is calculated as Area of base * Height/3. The Total volume can be plugged in via densitymas the mass relationship.. i.e. density = Mass/Volume => Mass = Volume Density
