Answer:

Rs. 333

Step-by-step explanation:

Area of the surface of the cuboidal box to be painted = surface area of the cuboidal box - area of the base

✔️Surface area of the cuboidal box = 2(L*W + W*H + L*H)

L = 6 cm

W = 4 cm

H = 2.5 cm

Surface area of the cuboidal box = 2(6*4 + 4*2.5 + 6*2.5) = 2(24 + 10 + 15) = 2(49)

Surface area of cuboidal box = 98 cm²

✔️Area of base = L*W

= 6*4 = 24 cm²

Area of the cuboidal box to be painted = 98 - 24 = 74 cm²

✔️Cost of painting 74 cm² at Rs. 4.50 per cm² = 74 × 4.50 = Rs. 333

Now divide the number of miles driven by the number of gallons:

414.7 / 14.5 = 28.6 miles per gallon.

A line segment is 20 units long. The line segment is translated up 6 units and left 8 units. The length of the resulting line se
lapo4ka [179]

Answer:

The length of the resulting line segment is 20 units and the length of a line segment is preserved on translation.

Step-by-step explanation:

The given length of the line segment is 20 units.

The line segment is translated up 6 units and left 8 units.

Here, the line segment is translated, so the whole line segment is at a new position after translation, there is no change in the length of the line.

So, the length of the line segment is preserved on translation.

After translation, the length of the line remains unchanged.

So, the length of the resulting line segment is 20 units.
