Math Problem Statement
Solution
From the image you've uploaded, you're asking to calculate the surface area of a rectangular prism (balok) with the dimensions of 9 cm, 8 cm, and 4 cm.
To find the surface area of a rectangular prism, the formula is: where , , and are the length, width, and height of the prism respectively.
Given:
Substituting these values into the formula, we get:
Let's calculate this.The surface area of the rectangular prism with dimensions is .
Would you like any further details on this calculation, or do you have any other questions?
- How would the surface area change if one dimension is doubled?
- What would be the surface area if all dimensions were increased by 2 cm each?
- How does changing the height affect the total surface area more than changing the width?
- Would you like to learn how to calculate the volume of this rectangular prism?
- How would the surface area calculation change if the shape were a cube instead of a rectangular prism?
Tip: When calculating the surface area of any prism, always verify the dimensions twice to avoid any calculation errors.
