Answer:

The length of a side of the base is 20 centimeters.

The area of a lateral side between the bases is about 126.5 square centimeters.

Step-by-step explanation:

It's a rectangular prism with a total volume of 800 cu cm, and a height of 20 cm.

So, the base has an area of... 800/20 = 40 sq cm.

The prism is a cube. NO. If it was a cube, the base would be 400 sq cm (20x20), since the height is 20.

The diagonal of the base is 4 centimeters. NO. with a base of 40 sq cm, it's impossible to have a diagonal of 4 cm. A diagonal would form a hypotenuse... and an hypotenuse is longer than the two other sides... an hypotenuse of 4 would mean for example sides of about 2 and 3... which gives 6 sq cm for the base, not 40.

The length of a side of the base is 20 centimeters. COULD BE. The base is 40 sq cm, it could have a side of 20 and the other of 2. Without knowing more about the prism than what's included in the question, we can't say YES and we can't say NO.

The area of a base is 40 square centimeters. Yes

The area of a lateral side between the bases is about 126.5 square centimeters. YES, since the height is 20, that would mean one side of the base would be roughly 6.325 cm... for a base area of 6.325 x 6.325 = 40 sq cm.

<h2>Answer:</h2>

1. The area of a base is 40 square centimeters.

2. The area of a lateral side between the bases is about 126.5 square centimeters.

<h2>Step-by-step explanation:</h2>

The statements that describe the prism are:

1. The area of a base is 40 square centimeters.

To find the volume of any rectangular prism, we use the formula $base \times height$ .

It is given that the volume of prism is 800 cubic centimeters and height is 20 centimeters.

Putting these values in the volume formula, to find base(B):

$800=B(20)$

$B=40$

Hence, area of base is 40 square centimeters.

2. The area of a lateral side between the bases is about 126.5 square centimeters.

Surface area of the prism

Trava [24]

length = 12 yd

width = 10 yd

height = 12 yd

diagonal = 19.697715603592 yd

total surface area = 768 yd2

lateral surface area = 528 yd2

bottom surface area = 120 yd2

volume = 1440 yd3

Can someone help me do this exercise

zubka84 [21]

The answer is 4 because if area is 28 meaning when you times the base and the height you'll get 28 therefore if you plug in 4 in the spot of x it should be 4+3 which equals 7 and since the value of x is 4 on top it must be 4 on the side too so you must do 7×4 which equals 28
