Answer: the length of the prism is 9cm
Step-by-step explanation:
The formula for determining the volume of a rectangular prism is expressed as
Volume = length × height × width
Volume = LWH
The length of the rectangular prism is three times the width.. It means that
L = 3W
The height and the width are the same. This means that
H = W
Therefore,
Volume = 3W × × W × W = 3W³
If the volume of the prism is 81 cubic centimeters, it means that
81 = 3W³
Dividing through by 3, it becomes
81/3 = 3W³/3
W³ = 27
Taking cube root of both sides, it becomes
W = 3
Therefore, the the length of the prism would be
L = 3W = 3 × 3
L = 9 cm
Answer is 2/3 + 2
Look at the image and if you need further explains I will be glad to.
The wording is a bit strange but I can tell you a ton is 2,000 pounds. 10,500 pounds would be equal to 5.25 tons.
Uhh that would be to much but I'm pretty sure if you download the app photo math and scan the question it will show you the slopes.
