I believe it would be 9,261 inches of water to fill the new cube.


To find the maximum capacity of a cube you have to multiply s*s*s (each s stands for one of its sides)

The side length happens to be 7. 7 times 7 times 7 is 343. If we triple that length now it’ll be 21. Multiply 21 by 21 by 21 it’ll give you 9,261 inches

Answer:

In a right triangle two of these are merged into the same square, so there are only two distinct inscribed squares. However, an obtuse triangle has only one inscribed square, one of whose sides coincides with part of the longest side of the triangle.

Find the area of a triangle with legs that are 9mm 6mm and 12mm
Sidana [21]

Here we are given the three sides of the triangle.

So we have Heron's formula to find its area.

Heron's formula is given by :

A= \sqrt{S(S-A)(S-B)(S-C)}

where A, B and C are sides of triangle and S is semi perimeter which is given by,

S= \frac{A+B+C}{2}

plugging values of A, B and C to find S

S= \frac{9+6+12}{2}

S=13.5

Now plugging values of A, B , C and S in Heron's formula

A= \sqrt{13.5(13.5-9)(13.5-6)(13.5-12)}

A=26.14 mm²

Answer: Area of triangle is 26.14 mm².

HELP PLEASE 3. Simplify the expression (5 points)<br> [(7 + 3) • 5 - 4] = 2 + 2
krok68 [10]

Answer: 46 or 46=4

Step-by-step explanation:

Do what's in the Parenthesis first so 7+2=10 which now give you the equation

[10x 5-4]=2+2

Now we Multiply so we do 10x5 which is 50 so that now gives us the equation[50-4]=2+2

Now we add the 2+2 which is 4 giving us the equation [50-4]=4

Now we subtract 50-4 giving 46

46=4

Delvig [45]

Answer:

Below.

Step-by-step explanation:

Letter P is drawn - Impossible because there is no paper with P on it.

Letter drawn is a consonant - Likely because there are 6 out of 8 letters which are consonants.

Letter drawn is a vowel - Unlikely because there are only 2 vowels out of 8 letters.

Letter drawn is one of the first ten letters in the alphabet - Equally likely as there is 4 of these out of a total of 8.

Letter is L - Unlikely as there is only 1 piece of paper with L on it.

The paper draw has one letter on it  - Certain as there is a letter on all the pieces of paper.
