A cuboid with a depth of 4 cm but a length and width of x cm is cut out from one corner of the original cuboid as shown (the original cuboid has dimensions of 10x8x4 cm). The remaining shape has a volume of 199. Calculate the value of x.

Correct answer:

x =  5.5 cm

Step-by-step explanation:

a=10 cm b=8 cm c=4 cm  V1=a b c=10 8 4=320 cm3 V2=199 cm2  V1  x x c = V2  x x c=V1V2  x=cV1V2=4320199=211 cm=5.5 cm
