The total height of the combination of solids is:
Show Hint
- 66 mm
- 40 mm
- 106 mm
- 118 mm
The Correct Option is C
Solution and Explanation
Let us extract the vertical dimensions of the two individual solids from the isometric drawing provided:
• Height of the lower horizontal triangular prism ($h_1$) = $40\text{ mm}$
• Vertical height of the upper hexagonal pyramid ($h_2$) = $66\text{ mm}$
Step 2: Calculating Total Assembly Height:
Since the hexagonal pyramid is placed coaxially on top of the flat upper rectangular face of the triangular prism, the total vertical height ($H$) of the combined assembly is simply the sum of their individual heights: $$H = h_1 + h_2 = 40\text{ mm} + 66\text{ mm} = 106\text{ mm}$$
Step 3: Conclusion:
Therefore, option (C) is correct.
