The value of given expression when m = 3 is 27
<h3><u>Solution:</u></h3>
Given expression is 
We have to evaluate the given expression for m = 3
To find for m is equal to 3, substitute m = 3 in given expression
From given expression,

Plug in m = 3 in above expression
------ eqn 1
We know that,
can be expanded as,

Applying this in eqn 1, we get

Simplify the above expression

Therefore, for m = 3 we get,

Thus value of given expression when m = 3 is found
Answer:
5 cm
Step-by-step explanation:
Here, we want to get the length of each box edge
Let the length be s
Mathematically, the volume of a cube is s^3
Thus;
s^3 = 125
s^3 = 5^3
s = 5 cm
Let's find area of the base.: 5x4.3=21.5, 21.5/2=10.75
Area of the Faces : 5x3=15/2=7.5x4=30
Let's add 10.75 +30=40.75
Answer:
85.5
Step-by-step explanation:
because you have to add 1/2 and 90cents =90.5 then you have to subtract 5 away and your answer is 85.5
