A right rectangular prism has edges of 8 feet, 4 feet, and 1/2 foot. How many cubes with side lengths of 1/2 foot would be neede

Ksenya-84 [330]

Answer:

Step-by-step explanation:

From the question we are told that

Edges of 8 feet, 4 feet, and 1/2 foot

Generally the volume V_p of the right rectangular prism is mathematically represented as

$V_p=8*4*0.5$

$V_p=16$

Generally volume of the cube V_c is mathematically given as

$V_c =(\frac{1}{2})^3$

$V_c =\frac{1}{6}$

Therefore total number of cubes is given as

$V=\frac{V_p}{V_c}$

$V=\frac{16}{\frac{1}{6}}$

$V=96$

Is it true 4 and -4 have a sum of 0

mafiozo [28]

Answer:

Yes, 4 + -4 = 0.

Think of it like a number line: The number four is 4 units to the right of the center which is 0, and the number negative four is 4 units to the left of the center. When you add them together, those distances cancel out, and you just get 0.
