6.4 is the width and the height is 7.8 what is the lateral and surface area of the square pyramid

Surface area of the square pyramid is 140.8 sq unit.

Step-by-step explanation:

Given,

Length (b) of each side of the square base = 6.4 unit

Height (h) of the pyramid = 7.8 unit

To find the surface area of the square pyramid.

Formula

Surface area of the square pyramid = 2bh+ sq unit

Hence,

Surface area of the square pyramid = 2×6.4×7.8+ sq unit

= 99.84 + 40.96 sq unit = 140.8 sq unit.

i can you with this question sweetie!

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
