The figure shows a block of stone measures 8 cm by 5 cm by 2 cm and has a density of 2.5 g/cm3 what is the volume of the stone?

what is the mass of the stone?

Step-by-step explanation:

The volume of the stone = 8 × 5 × 2 = 80

Using density = mass / volume

So 2.5 = mass / 80

2.5 × 80 = mass

200 = mass

please give me brainliest answer  

volume:

(8cm×5cm×2cm)=80cm³

I don't know the mass , sorry

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
