A shipping carton for a rolled-up poster has the shape of a triangular prism. Each end of the carton is a triangle with a base 6 inches long and a height of 5 inches. The length of the carton is 32 inches. If you answer we can chat ( : and I'll thank you in a big way!

Answers

I am guessing you are wanting to find the volume.

Volume= area of cross-section × length

The area of the cross-section is the triangle is 15 cm². 15 cm² × 32cm is 480cm³. Therefore the answer is 480cm³

If you are finding the surface area, the two triangles add up to 30cm. Then each rectangle is 160cm. There are 3 rectangles and 160x3= 480. 480+30= 510cm.

The surface area is 510cm and the volume is 480cm³.

Round each number to the nearest hundredth. what is the best estimate for the answer to 434.657 102.494?

Answers

434.657, hundredth digit is 5, after the 5 is 7, since the 7 is more than 5, we add 1 to the hundredth digit 5, to make it become 6.

434.657 ≈ 434.66 to the nearest hundreth.

102.494, hundredth digit is 9, after the 9 is 4, since the 4 is less than 5, we the hundredth digit remains as 9.

102.494 ≈ 102.49 to the nearest hundreth.

Hope this helps.

102.49 hope helps!!

Step-by-step explanation:

A faucet leaks 4 oz. of water per minute. How many gallons of water are wasted in a year? (128 oz. = 1 gallon)

Answers

Answer: 16,425 gallons are wasted a year

Step-by-step explanation:

First find out how many minutes there are in a year then multiply it by how much oz the faucet leaks every years then convert it into gallons.

There are 525,600 minutes in a year now multiply it by 4.

525,600 * 4 = 2,102,400 So there are more than 2 million oz wasted in a year so now convert it to gallons.

If there are 128 oz for every gallons the divide 2,102,400 by 128 to find out how many gallons are wasted a year.

2,102,400 / 128 = 16,425

Final answer:

The faucet wastes 16,425 gallons of water in a year by leaking 4 oz. per minute. This is calculated by first determining the total ounces of water wasted in a year, and then converting it into gallons.

Explanation:

The question wants to know how many gallons of water are wasted in a year by a faucet that leaks 4 oz. of water per minute. To solve this, let's first convert everything into consistent units, and then use simple multiplication to find the answer.

First, remember that there are 60 minutes in an hour, 24 hours in a day, and 365 days in a year. Thus, the faucet wastes 4 * 60 * 24 * 365 = 2,102,400 ounces of water in a year.

Now, convert this to gallons. We know that 1 gallon = 128 ounces. Therefore, the faucet wastes 2,102,400 / 128 = 16,425 gallons of water in a year.
