All the edges of a cube have the same length. Tony claims that the formula SA = 6s, where s is the length of

Answer:

Here's what I get

Step-by-step explanation:

a. Net of a cube

Fig. 1 is the net of a cube

b. Does the formula work?

Tony's formula works if you ignore dimensions.

There are six squares in the net of a cube.

If each side has a unit length s, the total area of the cube is 6s.

c. Will the formula work for any rectangular prism?

No, because a rectangular prism has sides of three different lengths — l, w, and h — as in Fig. 2.

d. Area of a rectangular prism

A rectangular prism has six faces.

A top (T) and a bottom (b) — A = 2×l×w

A left (L) and a right (R) — A = 2×l×h

A front (F) and a back (B) — A = 2×w×h

Total area = 2lw + 2lh + 2wh

If l = 5 m, w = 6 m and h = 8 m,

$\begin{array}{rl}A &=& \text{2$\times$ 5 m $\times$ 6 m + 2$\times$ 5 m $\times$ 8 m + 2 $\times$ 6 m $\times$ 8 m}\\&=& \text{60 m}^{2} + \text{80 m}^{2} + \text{96 m}^{2}\\&=& \textbf{236 m}^{2}\\\end{array}$

Can you solve: 6/5=n+2/2n-3

OverLord2011 [107]

solving $\frac{6}{5}=\frac{n+2}{2n-3}$ we get value of n: $n=4$

Step-by-step explanation:

Solving the expression:

$\frac{6}{5}=\frac{n+2}{2n-3}$

Solving:

$\frac{6}{5}=\frac{n+2}{2n-3}\\Cross\,\,multiply:\\6(2n-3)=5(n+2)\\Simplifying:\\12n-18=5n+10\\Combining\,\,like\,\,terms:\\12n-5n=10+18\\7n=28\\n=\frac{28}{7}\\n=4$

So, solving $\frac{6}{5}=\frac{n+2}{2n-3}$ we get value of n: $n=4$
