Problem 1

What is the difference of cubes for 8³ and 3³?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Use the formula: a³ - b³ = (a - b)(a² + ab + b²) a = 8, b = 3 8³ - 3³ = (8 - 3)(8² + 8*3 + 3²) = 5(64 + 24 + 9) = 5(97) = 485

Explanation

By applying the formula, we substitute 8 for 'a' and 3 for 'b', and perform the operations to find the difference of cubes.

Problem 2

Calculate the difference of cubes for 5³ and 2³.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Use the formula: a³ - b³ = (a - b)(a² + ab + b²) a = 5, b = 2 5³ - 2³ = (5 - 2)(5² + 5*2 + 2²) = 3(25 + 10 + 4) = 3(39) = 117

Explanation

Substituting 5 for 'a' and 2 for 'b', we apply the formula and calculate the difference of cubes.

Problem 3

Find the difference of cubes for 10³ and 6³.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Use the formula: a³ - b³ = (a - b)(a² + ab + b²) a = 10, b = 6 10³ - 6³ = (10 - 6)(10² + 10*6 + 6²) = 4(100 + 60 + 36) = 4(196) = 784

Explanation

By applying the formula with 'a' as 10 and 'b' as 6, we calculate the difference of cubes.

Problem 4

What is the result of the difference of cubes for 12³ and 7³?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Use the formula: a³ - b³ = (a - b)(a² + ab + b²) a = 12, b = 7 12³ - 7³ = (12 - 7)(12² + 12*7 + 7²) = 5(144 + 84 + 49) = 5(277) = 1385

Explanation

Using the values 12 for 'a' and 7 for 'b', we apply the formula to find the difference of cubes.

Problem 5

Determine the difference of cubes for 15³ and 9³.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Use the formula: a³ - b³ = (a - b)(a² + ab + b²) a = 15, b = 9 15³ - 9³ = (15 - 9)(15² + 15*9 + 9²) = 6(225 + 135 + 81) = 6(441) = 2646

Explanation

Substituting 15 for 'a' and 9 for 'b', we calculate the difference of cubes using the formula.
