STALIN [3.7K]

This the problem with non-SI units, conversion is such a nightmare. Anyhow, given $98 per cu.yd and total cost of $72.59, the volume of concrete is 0.7404 cu.yd. Converting the given dimensions to yards:

3.33 yd x (1/12) yd

Solving for the unknown dimension given volume and 2 other dimensions:

.7407 cu. Yd = (3.333 yd)(1/12 yd)(x)

X = 2.6678 yd or 8 feet

How many cubes with side lengths of 1/3 cm does it take to fill the prism?

user100 [1]

Answer:

The number of cubes that fill the prism is 24

Step-by-step explanation:

Given as :

The length of cube (l) = $\frac{1}{3}$ cm

The length of prism (L) = 1 cm

The width of prism (w) = 2 $\frac{2}{3}$ = $\frac{8}{3}$ cm

The height of prism (h) = $\frac{2}{3}$ cm

Let the number of cubes that fill the prism = x

Now, Volume of cube with length (l) = l³ cm³

Or, Volume of cube with length (l) = $(\frac{1}{3})^{3}$ cm³

Or, Volume of cube with length (l) = $(\frac{1}{27})$ cm³

Again , Volume of prism = $\frac{1}{2}\times Length \times width \times height$

Or, Volume of prism = $\frac{1}{2}\times 1 \times \frac{8}{3} \times \frac{2}{3}$

Or, Volume of prism = $(\frac{8}{9})$ cm³

<u>So , The number of cubes to fill prism </u>

The number of cubes × Volume of cube = Volume of prism

Or, x × $(\frac{1}{27})$ cm³ = $(\frac{8}{9})$ cm³

or x = $\frac{8\times 27}{9}$ = 24

Hence The number of cubes which fill the prism is 24 Answer

I have a homework about subtracting Integers and i don't get what -9 - 5, 31 - 48, ang -6 - 7 is

Alexxandr [17]

Well remember this:
When the signs are the same it is positive
When the signs are different make it negative

When you are subtracting a negative and positive, it is going to be like adding
for example:
-9 - 5 = -14
You just add 9 and 5 to get 14, the signs are different so it is going to be negative. ONLY WHEN YOU ARE SUBTRACTING NEGATIVES
