Question

. The length of a cuboid is 5 cm, breadth is 4 cm and height is 3 cm. a) find the volume of the cuboid. The cuboid is made up by metal. If the weight of the metal per cubic cm is 110 grams. b) Find the total weight of the cuboid in kilograms. If the cost of the metal per cubic cm is £ 11.50, c) Find the cost of metal of the cuboid.

Answer this Project

Answer 1

Answer:

Step-by-step explanation:

Volume=Lenght*Breadth*Height

Volume=5*4*3

Volume=60 cubic cm

Weight per cubic is 110 grams

Total weight=60*110

Total weight=6600grams

Cost per cubic cm= £11.50

Cost=11.50*60

Cost=£690

Answer 2

Answer:

((((((((A)))))))

Volume of a cuboid

$= length \times breadth \times height \\ =( 5 \times 4 \times 3 ) \: {cm}^{3} \\ = 60 \: {cm}^{3}$

((((((((B))))))))

weight of 1 cc metal = 110 gm

total weight of cuboid

$=( 110 \times 60) \: gm \\ = 6600 \: gm \\ = 6.6 \: kg$

((((((((C))))))))

cost of 1 cc metal= 11.5

cost of the metal required in cuboid

$= 11.5 \times 60 \\ = 690$
