Answer:

D. 30%

Step-by-step explanation:

This is the answer because:

1) When you convert decimals to percents, you have to remember the two main decimal places:

0.0<u>0</u> = The hundredths place

0.<u>0</u>0 = The tenths place

2) Whenever there is a decimal that is in the hundredths place, it will equal a one digit percent. For example, 0.07 = 7%.

3) Whenever there is a decimal that is in the tentsh place, it will equal a two digit number. For example, 0.3 = 30%.

4) Another way to solve it is to convert the decimal to a percentage by multiplying the decimal by  100 .

Therefore, the answer is 30%.

Hope this helps! :D

All the edges of a cube have the same length. Tony claims that the formula SA = 6s, where s is the length of
Darina [25.2K]

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}
