Răspuns:

Explicație pas cu pas:

inΔ dreptunghic VOB  avem  VO=12   OB=1/2DB=10√2/2=5√2

a)muchia lat VB²=VO²+OB²= 12²+50=144+50=194  VB=13,92

b)apotema Vm

in Δ dreptunghic VOM  VO=12  OM=L/2=5

VM²=OM²+VO²=25+144=169  VM=13

c)Ab=l²=10²=100 cm²

d)Al=4(VM×AB)/2=2(13X10)=260 CM²

e)At=Al+Ab=260+100=360cm²

f)V=Ab×VO/3=100×12/4=300CM³
