For a square brick, the ratio of length to width is 2:1, and the ratio of height to width is 2:1. The total length of all edges of this brick is 140 cm. What is the length, width and height


If the width is x, the length is 2x and the height is 2x
2X*4+2X*4+X*4=140
X = 7 cm
It is 14 cm long, 14 cm high and 7 cm wide
