Since painting is done on outer surface of cubical block we will have to find its surface area which is given by-
- <u>where a is side of the cube </u>
Now,
Thus it would cost $ 307.2 to paint the entire cubical block.
Answer:
Volume = 567 cm³
Step-by-step explanation:
The formula for the volume of a rectangular prism is
L x W x H
where
L = length
W = width
H = Height
Here, L=9 cm
W=7 cm
and H=9 cm
so
Volume = 9 x 7 x 9 = V = 567 cm³
I think I know what you're asking. You know that 4+4=8 so you can just subtract 1 from that to get 7.
Answer:
X > - 7.5
Step-by-step explanation:
1/X + 1/3 < 1/5
1/X + 1/3 < 1/5
Step one:collect like terms
1/X < 1/5 -1/3
Step two: Find the L.C.M of the R.H.S which is 15
1/X < 3-5/15
1/X < -2/15
1/X < -2/15
Step three: Take the reciprocal of both sides.
X < 15/-2
Dividing through by -2 changes the inequality sign, Hence
X > -7.5
