0.35x4
please help me

0.35*4=1.40

Step-by-step explanation:

Think of doing 35*4 but dividing the result by 100, or 2 decimal places to the left:

35*4 = 35*2*2 = 70*2 = 140

140/100 = 1.40

So, 0.35*4=1.40

1.4

Step-by-step explanation:

You can use a calculator or you can try it using this method:

4 * 0.05 = 0.2

4 * 0.3 = 1.2

1.2 + 0.2 = 1.4

Solution: The cuboid has a square base and a volume of 448 cc. If the height is 7 cm, the base area = 448/7 = 64 cm^2 or the sides are 8 cm x 8 cm. The lateral surface area = 4{8*7} = 224 cm^2. The total surface area = 224 + 2*448 = 1120 cm^2.
