If you roll a fair six-sided die and a fair four-sided die, what is the probability that the dice add to 6 or higher

Lena [83]

Okay so you have to figure out all the possible ways to get six or higher. between a 6 sided dice and a 4 sided dice. We do 6*24 to find all the possibilities.

The probability of getting a 6 or higher is 14/24

What is the volume of A cube with the surface area of 600 in.²

GrogVix [38]

Answer:

1000 in³

Step-by-step explanation:

A cube has 6 square faces

Given the surface area of the cube = 600 in², then

The area of 1 face = 600 ÷ 6 = 100 in²

The area of a square = s² ( where s is the measure of a side ), thus

s² = 100 ( take the square root of both sides )

s = $\sqrt{100}$ = 10

The volume (V) of the cube = s³, so

V = 10³ = 1000 in³
