Ответ: S=2361 2/3
V=63 916 2/3
Пошаговое объяснение:
а=b+3 h=a+2=>h=b+3+2=b+5
2a+2b+2h=116
2(b+3)+2b+2(b+5)=116
2b+6+2b+2b+10=116
6b+16=116
6b=116-16
6b=100
b=100÷6
b=50÷3=16 2/3
a=16 2/3 +3=19 2/3
h=19 2/3 +2=21 2/3
S=(a+b)×h=(16 2/3 +19 2/3)×21 2/3=36 1/3 ×21 2/3=(109×65)÷3=2361 2/3
V=a×b×h=16 2/3 × 19 2/3 ×21 2/3= (50×59×65)÷3=63 916 2/3
