A storage container consists of a box of length 90cm, width 42 cm and height 34 cm, and a lid

Ivanshal [37]

Answer:

20079.05 cm^2,

Step-by-step explanation:

Surface area of the box without the lid

= 90*42 + 2(90*34) + 2(42*34) = 12756.

Now find Surface area of the half cylinder:

The diameter of the 2 half circles = 42 so the radius = 21.

The area of the lid

= 2 + 1/2 π (21)^2 + π r * 90

= 7323,052

Total = 20079.052

Using this formula, what is the acceleration of an object with F = 7.92 newtons and m = 3.6 kilograms? Express your answer to th

g100num [7]

We have to use the following formula which is

$F = m * a$

Given values of F and m are 7.92 Newtons and 3.6 kilograms .

Substituting these values in the formula, we will get

$7.92 = 3.6 a$

To solve for a, we have to divide both sides by 3.6 that is

$a = \frac{7.92}{3.6}=2.2$

And that's the required answer .
