Find the volume of a rectangle block of ice 2 feet by 3 1/2 feet by 1 1/2. the volume of the rectangular block of ice is ( simplify your answer)

The answer is 80.5!

Step-by-step explanation:

The reason to the answer is because volume of a cuboid is l×B×H

(Substitute the values)  L = 2 , B = 3.5 , H = 11.5

2 × 3.5 × 11.5

Therefore, when we multiply these numbers we get, the answer 80.5!

I hope this answer helps!

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

thats one
