Answer:
71.3 ft
Step-by-step explanation:
Oliver has a piece of string that is 214 ft long. He needs to cut this string into 3 pieces that are all the same length.
To find the length that each piece should be, we divide the length of the string by 3:
214 / 3 = 71.3 ft
Each piece should be 71.3 feet long.
I'm pretty sure it is 155
The lateral area of the tea bag is the sum of the areas of the four triangles.
LA = 4 x (1/2)bh
Substituting,
LA = 4 x (1/2)(4 cm)(5 cm) = 40 cm²
The surface area is the sum of the lateral area and the area of the base.
SA = LA + BA
SA = 40 cm² + (4 cm)(4 cm) = 56 cm²
