Rama09 [41]

Answer: The sash will have 20 diamonds when it is completed.

Step-by-step explanation:

Given: The length of American sash= 8 feet

Since, Joseph wants to add a diamond shape every 0.4 ft along the sash.

Therefore, the number of diamonds he will need to complete the sash= $\frac{8}{0.4}$

⇒ The number of diamonds he will need to complete the sash= $\frac{80}{4}=20$

Hence, the number of diamonds he will need to complete the sash= 20
