A cuboid, the ratio of length, width and height is 4 to 3 to 2, and the total length of its edges is 108CM. What is the surface area and volume of the cuboid

A cuboid, the ratio of length, width and height is 4 to 3 to 2, and the total length of its edges is 108CM. What is the surface area and volume of the cuboid

Surface area 468 cm2
Volume 648 cm3

A cuboid with a volume of 36 cubic centimeters is cut off from a cuboid, and what is the surface area of a cuboid with a length of 3 centimeters

The rest is a 3*3*3 cube, so the cross-sectional area is 9, so the length of the section is 36/9=4
So the original cuboid is 3*3*7
Surface area =3*7*4+3*3*2=102 cm2
