Quadrilateral prism

Calculate the surface of a quadrilateral prism according to the input:
Area of the diamond base S1 = 2.8 m², length of the base edge a = 14 dm, the prism height 1,500 mm.

Correct answer:

S =  14 m²

Step-by-step explanation:

$$\begin{gathered} S_1=2.8{\text{m}}^2 \\ a=14\text{dm}\to \text{m}=14:10\text{m}=1.4\text{m} \\ h=1500\text{mm}\to \text{m}=1500:1000\text{m}=1.5\text{m} \\ o=4\cdot a=4\cdot 1.4=\frac{28}{5}=5.6\text{m} \\ S=2\cdot S_1+o\cdot h=2\cdot 2.8+5.6\cdot 1.5=14{\text{m}}^2 \end{gathered}$$
