Answer:

THE ANSWER IS GIVEN.............

Step-by-step explanation:

HEYA MATE,

NOW,

1. VOLUME OF THE WOOD IN THE BOX IS,

 

        LENGHT = 27 - 1.5*2 = 24cms ,  BREADTH = 19 - 2*1.5 = 16cms

                                   HEIGHT = 11 - 1.5 * 2 = 8cms.

        NOW,

        VOLUME = LBH = 24 * 16 * 8 = 3072cms³.

      2. NOW,

           COST    \     cm³         = 5.50 rupees

           COST OF 3072 cms³ = 5.50 * 3072 ⇒ 16896 rupees.

      3. NOW,

          NUMBER OF CUBES THAT CAN BE PLACED = VOLUME       OF BOX\4*VOLUME OF CUBE

         ⇒ 3072 \ 4 * 4 * 4 ⇒ 3072\64 ⇒ 48.

Answer 2

Area of the wood of closed box of given dimension = 2×(27×19 + 19×11 + 27×11 ) = 1019 sq.cm

volume of wood = 1019×1.5 = 1528.5 cubic cm

cost of wood = 1528.5×1.5 = Rs. 2292.75
