Given a rectangular prism of ABCD.EFGH has length, width, and height are 12cm, 5cm and 4cm respectively.
Determine :a. The length of diagonal face BDb. The length of diagonal of a rectangular prism HB

GHa. Since ∆BAD has a
right angle on A, then
BD2 =AB2+AD2 BD2 = 122+52
BD2 =169BD =13b. Since ∆BDH has a right angle on D, thenHB2 =BD2+DH2
HB2 = 132+42
HB2 =169+16HB2 = 185HB =
