Surface and volume od cuboid

Content area of the square base of cuboid is Sp = 36 cm2 and its height 80 mm. Determine its surface area and volume.

Result

S =  264 cm2
V =  288 cm3

Solution:

S1=36 cm2 v=80 mm=80/10 cm=8 cm a=S1=36=6 cm o=4⋅ a=4⋅ 6=24 cm  S2=o⋅ v=24⋅ 8=192 cm2  S=2S1+S2=2⋅ 36+192=264 cm2S_{1}=36 \ \text{cm}^2 \ \\ v=80 \ mm=80 / 10 \ cm=8 \ cm \ \\ a=\sqrt{ S_{1} }=\sqrt{ 36 }=6 \ \text{cm} \ \\ o=4 \cdot \ a=4 \cdot \ 6=24 \ \text{cm} \ \\ \ \\ S_{2}=o \cdot \ v=24 \cdot \ 8=192 \ \text{cm}^2 \ \\ \ \\ S=2S_{1}+S_{2}=2 \cdot \ 36+192=264 \ \text{cm}^2
