Answer:

1/2 gallons

Step-by-step explanation:

since 1/3of the tank is already full and another 4 gallons fills it up

4 gallons= 2/3 of the tank or the tank is 6 gallons total

75% is equal to 3/4

6*3/4=4 1/2 gallons

since it is 1/3 or 4 gallons full

4 1/2 -4= 1/2

Answer:

Total area to be painted in gold = 24000 cm²

Step-by-step explanation:

Total height of the stairs = 120 cm

Total standing stairs = 4

Therefore, height or width of one standing stair as shown in the picture,

= \frac{120}{4}

= 30 cm

Length of every stair has = 100 cm

Every horizontal and vertical stair has the same area.

Area of one stair = Length × Width

                            = 100 × 30

                            = 3000 cm square

There are 4 horizontal and 4 vertical similar stairs to be painted in gold.

Total area to be painted in gold = 8 × Area of one stair

                                                     = 8 × (3000)

                                                     = 24000 cm²

Total area to be painted in gold = 24000 cm²
