A railway car is shaped like a rectangular prism with a length of 18 meters, a width of 3 meters, and a height of 4 meters.
larisa86 [58]

The volume of railway car is 216 cubic meters

<em><u>Solution:</u></em>

Given that, Railway car is shaped like a rectangular prism with a length of 18 meters, a width of 3 meters and a height of 4 meters

To find: volume of railway car

<em><u>The volume of rectangular prism is given as:</u></em>

v = l \times w \times h

Where,

"l" is the length and "w" is the width and "h" is the height of prism

From given question,

length = 18 meters

width = 3 meters

height = 4 meters

Substituting the values, we get

v = 18 \times 3 \times 4 = 216

Thus volume of railway car is 216 cubic meters

Please help, I do not understand this
Kryger [21]

Answer:

Step-by-step explanation:

The sin(30) = 1/2

The sin(30) = 1/2 = opposite / hypotenuse

Opposite = 7

hypotenuse = opposite / sin(30)

hypotenuse = 7 / (1/2) = 7 *2 / 1 = 14

The long side can be found using the Pythagorian Theorem.

a^2 + b^2 = c^2

a = 7

b = ?

c = 14

14^2 = 7^2 + b^2

196 - 49 = b^2

147 = c^2

147 = 3*7 *7

sqrt(b^2) = sqrt(3*7*7)

b = 7 sqrt(3)

1.<br> What is the value of p – (–3.5) when p = 8.2?
viktelen [127]
Well set it up first. You get: 8.2-(-3.5) so what you do is that you first subtract 8.2-3.5=4.7. Then you want to find out weather it is negative or positive. First point out which one is bigger in this case 8.2 is bigger and a positive so your answer would be positive. Answer: +8.2 or 8.2
