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, height of the prism 1,500 mm.

Correct result:

S =  14 m2

Solution:

S1=2.8 m2 a=14 dmm=14/10 m=1.4 m h=1500 mmm=1500/1000 m=1.5 m  o=4 a=4 1.4=285=5.6 m  S=2 S1+o h=2 2.8+5.6 1.5=14 m2S_{1}=2.8 \ \text{m}^2 \ \\ a=14 \ dm \rightarrow m=14 / 10 \ m=1.4 \ m \ \\ h=1500 \ mm \rightarrow m=1500 / 1000 \ m=1.5 \ m \ \\ \ \\ o=4 \cdot \ a=4 \cdot \ 1.4=\dfrac{ 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
