The perimeter of the shaded face of this cube is 12 centimeters. What is the volume of the cube in cubic centimeters?
Varvara68 [4.7K]

Answer:

1728

Step-by-step explanation: L(length) H(height) W(width)

volume = l x w x h

perimeter= L + W + L + W

perimeter = 12 + 12  + 12 + 12

volume = 12 x 12 x 12 because it' s a cube, and all sides are equal

= 1728

(i don't know if it's right though...)

Please help me with this one!
mezya [45]

Answer:

3.1 feet

Step-by-step explanation:

Use the Pythagorean Theorem to find 0.5x and then multiply it by 2 to find x.

1.4²+b²=2.1²

1.96+b²=4.41

b²=2.45

b=\sqrt{2.45}

b≈1.56524758

x≈1.56524758×2

 ≈3.13049517

 ≈3.1 ft
