There is a cuboid with a square bottom. If the height is increased by 5cm, it will be a square, and the surface area is increased by 200cm2. What are the surface area and volume of the cuboid

There is a cuboid with a square bottom. If the height is increased by 5cm, it will be a square, and the surface area is increased by 200cm2. What are the surface area and volume of the cuboid

200 △ 4 △ 5 = 10 cm (edge length)
Surface area = 10 × (10-5) × 4 + 10 × 10 × 2 = 400 square centimeter
Volume = 10 × 10 × (10-5) = 500 cm3

A cuboid with a square bottom becomes a cube after its height is shortened by 5cm, and its surface area is reduced by 120cm2. The surface area of the original cuboid can be calculated

When the height is shortened by 5cm, it becomes a cube, and the surface area is reduced by 120cm
120÷5=24㎝
The bottom side length is 24 △ 4 = 6cm
Surface area of primitive cuboid
6＋5=11㎝
11×6×4＋6×6×2=336㎝²
Or 6 × 6 × 6 + 120 = 336 cm and 178;

The bottom of a cuboid is a square with a side length of 5 cm. Its surface area is 210 square meters. What's its height

If the surface area is 210 square meters (2100000-5 × 5 × 2) / (5 × 4) = hope the owner is satisfied
