Which figures should be used on the framing square to lay out the cross bridging for 38 mm x 254 mm (2"x 10") floor joists spaced 400mm (16") on centre?

235 mm and 360 mm
235 mm and 400 mm
254 mm and 260 mm
254 mm and 400 mm

The correct answer is: 254 mm and 400 mm

A and C are incorrect options because they do not account for the spacing of the floor joists. The cross bridging needs to be placed at the same spacing as the joists, which is 400mm. Both A and C would result in incorrect spacing and potentially compromise the stability of the floor. B is incorrect because it only uses one measurement (235 mm) which is not enough to accurately layout the cross bridging. The framing square requires two measurements to create precise angles for cutting. Therefore, the best option is D which uses both the width of the joist (254 mm) and the spacing (400mm) to create the correct angle for the cross bridging. It is important to use both measurements and follow the proper layout to ensure the stability and safety of the floor structure.
