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.

Answer:

its B for Ed

Step-by-step explanation:

well we know that 1/2 a gallon (or 0.5 gallons) is equal to 8 cups. So one gallon is 16 cups. (keep this in the back of your mind)

Now to find how many cups she drinks in a day, find out how many gallons she drinks in a week.

So 0.5 (7) = 3.5

Now compute to see how many cups are in 3.5 gallons.

Answers

simplify the equation with pemdas
first parentheses

distributive property
a(b+c)=(ab)+(ac)

(5y+2)2=(10y)+(4)
10y+4-96=0
10y-92=0
add 92 to both sides
10y=92
divide both sides by 10
y=9.2
