The cube shown has side length 0.7 metres. 0.7 m
Work out the total surface area of the cube.
Give your answer in square centimetres.
Note: Please make sure your final answer shows the correct unit
cm

294cm

Step-by-step explanation:

6 × a² (length of side)

6 × 0.7²

6 × 0.7 × 0.7 = 2.94m

Final answer = 294cm.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
