The density of water is 1 gram per cm3. An object floats in water if its density is less than water’s density, and it sinks if its density

is greater than water’s. Will a 1.17 gram pyramid whose base has

area 2 cm2 and whose height is 0.5 centimeters sink or float?

It will sink

Step-by-step explanation:

We first have to find the volume of the pyramid. Then, find the density and compare it to that of water.

The pyramid has a base area of and height is 0.5 cm. The volume of a pyramid is given as:

V = (a * h) /3

where a = base area and h = height of pyramid

Therefore:

V = (2 * 0.5) / 3 =

Density is given as:

D = mass / volume

The mass of the pyramid is 1.17 g.

Therefore:

Density = 1.17 / 0.33 = 3.54

Since its density is greater than that of water, it will sink.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
