Answer:

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

Step-by-step explanation:

A parking lot can hold cars and small trucks. The scatter plot shows how many cars and trucks parked at the parking lot each day

SashulF [63]

What is the daily average number of trucks parked at the lot that week?

Answer: From the scatter plot, we can see the number of trucks at the parking lot each day for a week. The numbers are:

2, 2, 3, 3, 3, 4, 5

Therefore, the daily average number of trucks parked at the lot that week is:

$Average=\frac{2+2+3+3+3+4+5}{7}$

$=\frac{22}{7}$

$=3.1$ rounded to nearest tenth.

What is the daily average number of cars parked at the lot that week?

Answer: From the scatter plot, we can see the number of cars at the parking lot each day for a week. The numbers are:

2, 3, 4, 4, 5, 5, 6

Therefore, the daily average number of cars parked at the lot that week is:

$Average=\frac{2+3+4+4+5+5+6}{7}$

$=\frac{29}{7}$

$=4.1$ rounded to nearest tenth.
