The Toblerone company packages chocolate candy in a container that is a triangular prism. The base is an
dolphi86 [110]

Answer:

76017.69 mm²

631000 mm³

295045.04 mm³

Step-by-step explanation:

Surface area = bh + 2ls + lb

Since the sides of the triangular prism are equal (equilateral triangle) = 60 mm each

Height = 405 mm

The surface area of triangular = 76017.69 mm

The volume of triangular prism :

1/2 * base * height * length

Volume = 631000 mm³

If amount of chocolate inside = 335954.96 mm3

Empty space =

Volume of triangular prism - amount of chocolate inside

631000 - 335954.96

= 295045.04 mm³

How do you solve for sides a and b of a triangle when you know the value of c?
sasho [114]
Assuming you have some angle measures, you could use the Law of Sines to solve for the missing side lengths, which states that,
\frac{a}{sinA}= \frac{b}{sinB}= \frac{c}{sinC},
where a, b, and c correspond to the given sides you have, and A, B, and C represent the angles you have.

In this scenario, you would have to have the values for c (which we do), and have the angle measure of C. In addition, we would also need an angle measure that is either A or B.

Hope this helps a bit!

Write the following as a root in radical form 2^-4/5
erastovalidia [21]

Answer:

Given that:

=2^(-4/5)

This means that 2 is the base and -4/5 is the exponent.

To change it in radical form:

  • firstly the denominator would be written with radical sign
  • Then the negative sign with 4 will be removed by inverting the base.
  • Then the fraction will be simplified according to the exponent (power)
  • All the steps are performed below:

=\sqrt[5]{2^{-4} } \\=\sqrt[5]{1/2^4}\\ =\sqrt[5]{1/16}

i hope it will help you!
