Problem 1

Find the edge length of a cube, where the surface area of the cube is 6241 cm².

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

The surface area of a cube = 6a² So, the surface area of a cube = 6241 cm² So, the edge length = √(6241/6) ≈ 79. The edge length of the cube is approximately 79 cm.

Explanation

The edge length of the cube is approximately 79 cm. Because the surface area is 6241 cm², we find the edge length as √(6241/6) ≈ 79.

Problem 2

Sarah is designing a square garden plot with a side length of 79 meters. Each square meter costs $5 to landscape. What is the total cost to landscape the entire plot?

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

The side length of the garden plot = 79 meters The cost to landscape 1 square meter = $5 To find the total cost, calculate the area of the plot, Area of the plot = side² Here, side = 79 Therefore, the area of the plot = 79² = 79 × 79 = 6241. The cost to landscape the plot = 6241 × 5 = $31,205. The total cost = $31,205

Explanation

To find the cost to landscape the plot, we multiply the area of the plot by the cost per square meter. So, the total cost is $31,205.

Problem 3

Find the area of a circle whose diameter is 79 meters.

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

The area of the circle = 4909.24 m²

Explanation

The area of a circle = πr² Here, diameter = 79, so radius r = 79/2 = 39.5 Therefore, the area of the circle = π × (39.5)² = 3.14 × 39.5 × 39.5 ≈ 4909.24 m².
