Question
Two units of length used in ancient Egypt were cubits and palms, where 1 cubit is equivalent to 7 palms. The Great Sphinx statue in Giza is approximately 140 cubits long. Which of the following best approximates the length, in palms, of the Great Sphinx statue?
- 0.05
- 20
- 140
- 980
The correct answer is: 980
○ The concept used in this question is the concept of the equation.
○ In this question, an equation with one variable is used, which contains only one variable.
○ In equation, LHS = RHS, always.
○ While solving separate the variable term and constant to get the solution
- Step-by-step explanation:
○ Given:
1 cubit = 7 palms
The Great Sphinx statue in Giza is approximately 140 cubits long.
○ Step 1:
○ Convert length into palms
As it is given that,
1 cubit = 7 palms
Therefore, 140 cubits will be,
= 140 × 7
= 980
Hence, the length, in palms, of the Great Sphinx statue is 980 palms.
- Final Answer:
Correct option is,
Option D. 980.
