Answer:
A) Vol_10_cubes = 2*(5^4) inch^3
B) Area_10_cubes = (2^2)*3*(5^3) inch^2
Step-by-step explanation:
A)The volume of a cube, as all sides are equal:
Vol_cube = (side)^3
side = 5 inches
Vol_cube = 5^3 inch^3
Since we have 10 cubes
10 = 2*5
Vol_10_cubes = 2*(5^4) inch^3
B) A cube has six faces, each with area equal to its squared side
Area_cube = 6*(side)^2
Area_cube = 6*(5)^2 inch^2
Area_10_cubes = 2*5*6*(5)^2 inch^2
Area_10_cubes = (2^2)*3*(5)^3 inch^2
Answer:
The Fraction 21/3+31/3=17 1/3
Answer: 14 & 8
14 + 8 = 22
14 - 8 = 6
Answer:
12 ≤ x - 7
Step-by-step explanation:
let "x" represent the number
The term decreased means subtraction.
The problem indicates that 12 cannot be greater than a number decreased by 7. Use ≤ which means less than or equal to.
≤ less than or equal to 12 means that 12 is the maximum value.
The amount of metal needed to make the metal stud for the costume is 12 unit²
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Given that the meatal stud does not have a base, hence:
Amount of metal needed = sum of area of triangular faces = 4(1/2 * 2 * 3) = 12 unit²
The amount of metal needed to make the metal stud for the costume is 12 unit²
