How do you calculate the mass of a solid copper cuboid with a density of 9.86 g/cm^3. The dimensions of the cuboid are 10 cm  by 3 cm by 5 cm​

step 1

Find the volume of the cuboid

V=(10)(3)(5)=150\ cm^3

step 2

Find the mass

we know that

To find out the mass multiply the density of the solid by its volume

so

m=(9.86)(150)=1,479\ g

dalvyx [7]

Answer:

68% increase and 91% increase

Step-by-step explanation:

220(1+x)=370 --  220(1+rate increase)=370

1+x=1.68

x=.68

220(1+x)=420  (370+50)=420

A.
well, to find the perimeter of a rectangle, it is 2(length+width)
using this, the perimeter of the tennis court is 2(2x+6+x)=2(3x+6)=6x+12
the perimeter of the basketball court is 2(3x-14+1/2x+32)=2(2 1/2x+18)= 5x+36
B. 
the difference is subtraction, so it'd be 6x-12-(5x+36)
C.
width is 2x+6
2x+6=36
2x=30
x=15
tennis: 15 by 36
basketball: 3*15-14= 31
1/2*15+32= 39.5
31 by 39.5
