Answer:
Step-by-step explanation:
Did you mean log (17*3)? If so, your log (17x3) becomes log 17 + log 3.
Did you mean log 17^3? If so, log 17^3 = 3 log 17.
Did you mean log 17*x*3? If so, this equals log 17 + log x + log 3

<u>Answer:</u>
1.95 cubic feet
<u>Step-by-step explanation:</u>
We are given that Emily stores her jewelry in a cube and the cube has a side length of 
feet.
feet in an decimal form is 1.25 feet.
We know that,
<em>volume of a cube = s
</em>
where <em>s</em> is the side length of the cube.
So substituting this value of side length of cube in the formula to get:
Volume of cube = 
= 1.95 feet

Answer: 14 square inches</h3>
Explanation:
There are 4 lateral faces for each of the three blocks. So that is 4*3 = 12 faces so far. Then there is the top and bottom face of the top and bottom block respectively. This brings the total up to 12+2 = 14 external faces.
Alternatively, we can note how 1 cube has 6 faces. So 3 cubes have 3*6 = 18 faces. However, 4 faces are hidden or they are not external faces when we combine the blocks as the diagram shows. So we have 18-4 = 14 external faces.
No matter which method you use, there are 14 external faces. Each face is 1*1 = 1 square inch, so the total surface area is 14*1 = 14 square inches.
