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

SashulF [63]

Answer:

0.083 repeating

Step-by-step explanation:

The chance of getting 3 on the first spin is 1/6 because there are 6 possible outcomes and 1/2 on the second spin because 1,3,5 are all odds and 2,4,6 are even and when you multiple them together you get 0.083 repeating.
