A flute case is shaped like a rectangular prism. The caseis 5inches tall, 3 inches wide, and has a volume of 255 cubic inches

Anna [14]

Answer:

The length of the case is 17 inches.

Step-by-step explanation:

A flute case is shaped like a rectangular prism with dimensions:

height = 5 inches;
width = 3 inches;
length = x inches.

The volume of the case is 255 cubic inches.

Use formula for the volume of the rectangular prism:

$\text{Volume}=\text{Width}\times \text{Length}\times \text{Height}$

Thus,

$255=5\cdot x\cdot 3\\ \\255=15x\\ \\x=\dfrac{255}{15}=17$

The length of the case is 17 inches.

Aaron has a 28.7 m length of rope. He uses 6.7 m of the rope

Bingel [31]

Answer:

first step is to minus 28.7 - 6.7=22 (I did the minus because I want to get the remaining length of the rope )

step 2 : is to divide 22 by 2 (because the question said they should divide it into two pieces )

then the answer you get from the division of 22/2 which is 11 that would be the final answer

meaning each tire swing is 11m
