Final answer:
The calculated surface area is 61.44 cm². To find the surface area and volume of each solid (sphere and cube), use the respective formulas and plug in the given measurements. Then round the results to the nearest tenth.
Step-by-step explanation:
To find the surface area and volume of each solid, we need to know which solids we are dealing with. However, based on the given measurements (4.0 cm, 2.4 cm, 3.2 cm, and 2.0 cm), we can calculate the surface area and volume of a sphere and a cube, both rounded to the nearest tenth.
Sphere:
Given the radius of a sphere, we can use the formula:
Volume of a sphere = (4/3) * pi * r^3
Surface area of a sphere = 4 * pi * r^2
Let's calculate it using the given radius:
Radius = 2.0 cm
Volume = (4/3) * 3.14 * (2.0)^3 = 33.49 cm³
Surface Area = 4 * 3.14 * (2.0)^2 = 50.24 cm²
Cube:
Given the side length of a cube, we can use the formula:
Volume of a cube = s^3
Surface area of a cube = 6 * s^2
Let's calculate it using the given side length:
Side Length = 3.2 cm
Volume = (3.2)^3 = 32.77 cm³
Surface Area = 6 * (3.2)^2 = 61.44 cm²
