What is the formula to calculate the surface area of a rectangular prism with a cube removed?

1 answer:

3 0

<span> 2ab + 2bc + 2ac the formula for the rectangular prism and i'm guessing you would find the answer to this than you would find your formula for the cube which is </span><span><span>6 a </span>2 and you would find that answer.
</span>You would take your total for the rectangular prism answer and subtract the cube answer from it and you would probably get your answer.
hope that helped?!

Answer:

x = 2.4/20= 0.12

Step-by-step explanation:

Multiply both sides by 4 to eliminate the fraction 1/4:

1 20

--- = ------

x 2.4

Next, we cross-multiply. This eliminates the fractions:

20x = 2.4

Dividing both sides by 20 results in an equation for x: x = 2.4/20= 0.12

The first side of a triangle is 2 inches shorter than the second side. The third side is 5 inches longer than the second side. I

fomenos

Let the length of second side be x" ,

So,
Length of first side = 2" shorter than second = ( x - 2 )"
Length of third side = 5" longer than second = ( x + 5 )"

=×=×=×=×=×=×=×=×=×=×=×=×=×=×=×=×=

$\text{Perimeter = sum of all sides }$

Given, perimeter = 33"

= > first side + second side + third side = 33"

= > ( x - 2 ) + x + ( x + 5 ) = 33

= > x - 2 + x + x + 5 = 33

= > 3x + 3 = 33

= > 3x = 30

$= \: > x = \frac{30}{3}$

= > x = 10

Hence, length of each side is

First side = ( x - 2 )" = ( 10 - 2 )" = 8 inches

Second side = x " = 10 inches

Third side = ( x + 5 )" = ( 10 + 5 )" = 15 inches

For every 6 students who purchase a bag of M&M’s, there are 5 students who purchase a pack of gum. Use M for the number of s

Assoli18 [71]

Answer:

M/6 = G/5

Step-by-step explanation:

We are given a relation between the numbers of students in two different groups. That relation can be used to write an equation.

<h3>Groups who bought M&Ms</h3>

If we consider M&M buyers to be 6 in a group, then the number of those groups is ...

M/6

<h3>Groups who bought gum</h3>

Similarly, the number of groups who bought gum will be ...

G/5

where there are 5 gum-buyers in each group.

<h3>Equation</h3>

The problem statement tells us that for each group of one kind, there is a matching group of the other kind. That is, the numbers of groups are equal:

M/6 = G/5
