Question

two cubes each of side 16 cm are joined end to end. find the total surface area and volume of the resulting cuboid

Answer 1

Answer:

surface area=2370cm2

Explanation:

if two cubes of length 16cm are joined, the resulting cuboid will be of dimensions

32cm by 15cm by 15cm

surface area will be

each end =→15×15=225cm2

one top/bottom=→32×15=480cm2

each side→32×15=480cm2

total surface area=2×(480+480+225)

surface area=2×1185=2370cm2

Volume =lbh
32*15*15=7200cm2 volume ans:)

Answer 2

Answer:

The whole floor vicinity of the ensuing cuboid is 2048 rectangular cm and the quantity is 8192 cubic cm.

Step-by-step explanation:

From the above question,

                   When two cubes are joined quit to end, they shape a cuboid with dimensions of sixteen cm (length), sixteen cm (width), and 32 cm (height).

To locate the whole floor vicinity of the ensuing cuboid, we want to calculate the place of all six faces.

The place of the pinnacle and backside faces is sixteen x sixteen = 256 rectangular cm each.

The place of the the front and again faces is sixteen x 32 = 512 rectangular cm each. The place of the left and proper faces is additionally sixteen x 32 = 512 rectangular cm each.

Therefore,

          The whole floor location of the cuboid is:

Total floor location = 2(256) + 2(512) + 2(512)

Total floor location = 2048 rectangular cm

To locate the quantity of the cuboid, we clearly multiply the length, width, and height:

              Volume = sixteen x sixteen x 32

              Volume =  8192 cubic cm

Therefore,

    The whole floor vicinity of the ensuing cuboid is 2048 rectangular cm and the quantity is 8192 cubic cm.
