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 .

Solve the formula x/4 + x/3 = 1
miskamm [114]

Answer:

x = 12/7

Step-by-step explanation:

in order to solve this formula x/4 + x/3 = 1

<u>solutio</u>n

x/4 + x/3 = 1

the first step to do is to take lcm of the left hand side

[3(x) + 4(x)] /12 = 1

[4x +3x]/ 12 = 1

7x/12 = 1

cross multiply

7x/12 = 1

7x = 12 × 1

7x = 12

divide both sides by 7

7x/7 = 12/7

x = 12/7

Two trains travel a 160 km track each day. The express travels 10 km h^-1 faster and take 30 minutes less time than the normal t
aniked [119]
Let s = the speed of the slower train in km/hrs+10 = the speed of the faster train in km/hrLet t = time in hrs for the slower train to go 160 kmt-5 = time in hrs for faster train to go 160 km---------------Slower train:(1)
160=s.t

Faster train:(2) 160=(s+10) .(t-.5)From (1)(1) t=160/s
use the relations given in following screenshot and then use quadratic equation.
