Calculate the total surface area of the cuboid of dimensions 6cm by 5cm by 7.5cm

Answer 1

SA = 2(6)(5) + 2(6)(7.5) + 2(5)(7.5) = .... cm^2

Answer 2

125

Answer 3

Calculate the total surface area of the cuboid of dimension 6cm by 5cm by 7.5

Answer 4

To calculate the total surface area of the cuboid, we need to find the area of each face and add them up.

The cuboid has six faces:
- Two faces with dimensions 6cm by 5cm
- Two faces with dimensions 6cm by 7.5cm
- Two faces with dimensions 5cm by 7.5cm

The area of each face is given by length x width.

Area of first face = 6cm x 5cm = 30cm²
Area of second face = 6cm x 5cm = 30cm²
Area of third face = 6cm x 7.5cm = 45cm²
Area of fourth face = 6cm x 7.5cm = 45cm²
Area of fifth face = 5cm x 7.5cm = 37.5cm²
Area of sixth face = 5cm x 7.5cm = 37.5cm²

Total surface area = Area of all six faces
= 30cm² + 30cm² + 45cm² + 45cm² + 37.5cm² + 37.5cm²
= 225cm²

Therefore, the total surface area of the cuboid is 225cm².
