<u>Answer:</u>
Below!
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- Length = Height = Width
- Volume = LHW = L³ = 64000
- Surface area = 6(area of a square)
<u>Part A Solution:</u>
- L³ = 64000
- ∛L³ = ∛64000
- => L = ∛40 x 40 x 40
- => L = 40 inches
Hence, the length is 40 inches.
<u>Part B Solution:</u>
We know that the length is 40 units. Since this is a cube, L must equal to W.
- => L² = 6(40 x 40)
- => L² = 6(1600)
- => 9600 square inches
Hence, the surface area is 9600 square inches.

Answer:
if the probability of a 6 is 1/5, the probability of “not six” is 4/5. The probability of a 6 on the first roll and not on the second is 1/5 x 4/5 = 4/25. The six could come on the second roll so that probability must be doubled. The overall probability of exactly one six is 8/25 or 0.32.

Answer:
$36.38
Step by step explanation:
First, we need to find out what 1% of $40 dollars is. To do this, we divide 40 by 100.
This gives us $0.40.
To then find out fifteen percent of $40, you then times $0.40 by 15.
This gives us 6 dollars.
Now, to work out the discount, we take 6 from 40.
$40 - $6 = $34
Now we have to work out the tax.
Again, we have to work out what 1% of $34 is.
This gives us $0.34
Then times that by 7 to find 7%
0.34 x 7 = $2.38
Since this is tax we have to add instead of subtracting.
$34 + $2.38 = $36.38 as the final bill.
