The surface area of a cuboid with a square cross section is 114 square centimeters. The largest cuboid is cut off and the surface area is 54 square centimeters, How much square centimeter has been subtracted from the surface area of the truncated cube wood?

The surface area of a cuboid with a square cross section is 114 square centimeters. The largest cuboid is cut off and the surface area is 54 square centimeters, How much square centimeter has been subtracted from the surface area of the truncated cube wood?

If the length is h and the edge is a, then
4ah+2a^2=114
4a(h-a)+2a^2=54
Subtracting a ^ 2 = 15
So surface area = 6A ^ 2 = 6 * 15 = 90
perhaps
(114-54) △ 4 = 15 (square centimeter) surface area of sawn cube: 15 × 6 = 90 (square centimeter)

The surface area of a rectangular wood with square cross section is 114 square centimeters. After sawing off the largest cube, the surface area is 50 square centimeters. What is the surface area of the cube?

The bottom area of the original cuboid: (114-50) △ 4 = 64 △ 4 = 16 (square centimeter) 16 × 6 = 96 (square centimeter) a: the surface area of the saw cube is 96 square centimeter

A rectangular wood with square cross section has a surface area of 114 square centimeters. After sawing out the largest cube, the surface area is 54 square centimeters
What is the surface area of the sawn cube wood in square centimeter?

Side area of cube = 4 side length × 1 side length = 4 side length and 178; = 114-54 = 60, side length and 178; = 15;
So the surface area of cube is 2 × 15 + 60 = 90 square centimeter
