A diagonal of a cube measures StartRoot 294 EndRoot cm. The diagonal of a face measures 14 cm. What is the length of an edge of
hram777 [196]

The side of the edge of the cube is 9. 9cm

<h3>How to determine the length</h3>

Given that the diagonal of a cube measures the square root of 294cm and the diagonal of a face measures 14cm

To find the edge of the face, we know that the face of the cube is a square

Formula for diagonal of a square = \sqrt{2a}

Where is the side of the square

We then have,

\sqrt{2a}  = 14

Make 'a' the subject

a = \frac{14}{\sqrt{2} }

Simplify the surd

a = \frac{14}{\sqrt{2} } × \frac{14}{\sqrt{2} }

a = \frac{14\sqrt{2} }{2}

a = 7\sqrt{2}

a = 9. 9cm

Therefore, the side of the edge of the cube is 9. 9cm

I think its easier to work out part (c) first:-

People who liked anything except burger  = 3/8 + 1/4 + 1/5 =  33/40

So the fraction who liked burgers = 7/40.

7/40 of the total liked burgers   so total people surveyed = (40/7) * 126 =  720

ANswer to c is 720.

a) Number who liked  chicken and laksa = (3/8 + 1/4) * 720  =  450 Answer

b)  Number who liked pasta =  1/5 * 720  =  144

Therefore  144-126  =  18 more people liked pasta than burger , Answer.
