  • 5. L= a×t/2 ×t
    = 6×8/2×18
    = 432 dm3
    6. LB=p×l×t
    =8×5×3
    =120
    LP=a×t/2×t
    = 5×3/2×8
    =60
    LS= 120+60
    =180 cm3
    7.LB=p×l×t
    =5×6×4
    =120
    LP=a×t/2×t
    =5×3/2×6
    =45
    LS=120+45
    =165cm3
    8.LP1=a×t/2×t
    =4×3/2×10
    =60
    LP2=a×t/2×t
    =5×5/2×3
    =37,5
    LS=60+37, 5
    =97,5cm3
