Sense this would be known to be a 'prism', we would them do the following key point:

l*w*h

Therefore, we would then multiply to following numbers which would be above.

(5*4*3=60)

Question #2.

The reason to why we would us 'square units' to answer in a area format would be because by doing so, it would then describe the surface of the area. And by knowing what you are measuring something by would be a whole lot easier.

This question requires us to draw a net, and from the net, find the surface area.

The nets are shown in the attached figures.  Dimensions of the sides can be interpreted by counting the grid.  Dimensions of the slanted sides all equal 5 inches in the second grid.

(A)
The net consists of 6 rectangles, namely
2*(4*5)=40 cm ²
2*(4*3)=24 cm ²
2*(5*3)=30 cm ²
Total area = 94 cm ²

(B)
The net consists of 5 polygons, including 3 rectangles and 2 triangles (base)
The total area is given by the sum of the polygons, namely,
1*(8*7)=56 in ²
2*(8*3/2)=24 in ²
2*(5*7)=70 in ²
Total area = (56+24+70) = 150 in ²

Each net is drawn by unfolding the edges until all faces are in the same horizontal plane.

Since we are measuring the sum of surface areas of each of the faces, the unit is in area units, such as cm ², or in ² .

in a xy-coordinate system line 1 has a slope of -3. If the points (2,16 and (5,t) are on line 1, what is the value of t?
Dimas [21]
We can use the formula y2-y1/x2-x1 to find our answer. So, we have : t-16/5-2 = -3. We simplify that to t-16/3 = -3. We can then multiply both sides by 3 to get t-16 = -9. Then we can add 16 to both sides to get t = 7.

Answer:

1.  Not a function.

2. This is a function.

3. This is a function.

Step-by-step explanation:

1. 13 maps on to 4 and -4 so not a function.

2 and 3 - these both pass the vertical line test so they are functions.
