How to find the total surface area of a rectangular prism?

1 answer:

3 0

If the length is taken as l , height is taken as h and breadth is taken as b . then

Area of the rectangular prism= 2( (l*b) + (b*h) + (h*l) )

hope that helps

Solve the equation sin theta = 0.3 to the nearest tenth. Use the restrictions 90degrees < theta < 180degrees.

Alexxandr [17]

We first do:
∅ = sin⁻¹(0.3)
∅ = 17.5°

To go into the second quadrant, we add 90°.
∅ = 17.5 + 90
= 107.5°
The answer is A.

Answer:

Stop and Save

Step-by-step explanation:

Find the cost of one apple in each place.

Quick Market:

Divide the total cost with the amount of apples:

1.08/3 = 0.36

The cost for one apple in quick market is $0.36

Stop and Save:

Divide the total cost with the amount of apples:

1.10/5 = 0.22

The cost for one apple in Stop and Save is $0.22

-----------------------------------------------------------------------------------------

$0.22 < $0.36 ∴ Stop and Save is cheaper than Quickmarket by $0.14, making Stop and Save your answer.

The side length of a square ice cube is claimed to be 1.0 inches, correct to within 0.001 inch. Use linear approximation to esti

Olenka [21]

Answer:

0.012

Step-by-step explanation:

Linear approximation says that,

$f(x) \approx f(x_o)+f'(x_o)(x-x_o)$

For a cube the surface area is $6x^2$ .

So the side is 1.0 inch in, the surface area is $=6\times1^2 = 6$ square inches.

In Linear approximation means you ignore the term $x_o^2$ , if $x_o$ is a small number, because then $x_o^2$ will be a very smalle number and that does not contribute much to the error.
