Cuboid box

Cuboid box have dimensions of 30 cm, 25 cm and 40 cm. Sketch its network and compute surface area of box.

Correct answer:

S =  5900 cm²

Step-by-step explanation:

$$\begin{gathered} a=30\text{ cm } \\ b=25\text{ cm } \\ c=40\text{ cm } \\ S=2\cdot (a\cdot b+b\cdot c+a\cdot c)=2\cdot (30\cdot 25+25\cdot 40+30\cdot 40)=5900{\text{cm}}^2 \end{gathered}$$
