One paint container is enough to paint all the faces of fifty 8 cm cubes.

Given

The paint can cover 20,000 cm^{2}

Side of square  = 8 cm

As the Total surface area of a cube is  6a^{2},

where a is the side of the cube.

The total surface area of one cube =  6 x 8^{2}

                                                          =  384 cm^{2}

Since there are fifty such cubes,

384 x 50

Total area to be painted = 19200 cm^{2}

Since 19,200 cm^{2} is less than 20,000 cm^{2} , it is possible to paint all the cubes.

Hence one paint container is enough to paint all cubes.

In each figure below find m ∠1 and m∠2, if a||b. Justify with<br> reasons your solution.
Mazyrski [523]

Answer:

m<1 = 130°

m<2 = 50°

Step-by-step explanation:

Since given that line a is parallel to line b, and <1 and 130° are interior angles that alternate each other, therefore:

m<1 = 130° (alternate interior angle theorem)

Also,

130° and <2 lie on same side inside the parallel lines cut across by the transversal, therefore,

m<2 + 130° = 180° (same side interior angles theorem)

m<2 = 180° - 130°

m<2 = 50°

A section of guttering can hold up to 20 litres of rainwater. The diameter is 11cm. Work out the length in metres.
m_a_m_a [10]

Answer:

2.1 m

Step-by-step explanation:

The gutter is in the shape of a cylinder.

Its volume is 20 liters and its diameter is 11 cm (0.11 m).

Its radius is half of its diameter => r = 0.055 m.

The volume in cubic metres:

1 litre = 0.001 cubic metres

20 litres = 20 * 0.001 = 0.02 cubic metres

The volume of a section of guttering is given as:

V = \pi r^2h

where h = length of the guttering

Therefore:

0.02 = \pi * 0.055^2 * h\\\\0.02 = 0.009503h\\\\h = 0.02 / 0.009503\\\\h = 2.10 m

The length of the section of guttering is 2.1 m long.
