Can you guys help me plsss
I do not get this work

160 square units

Step-by-step explanation:

We need to find the surface area of this figure, which is basically the areas of all the exterior sides.

Looking at the pyramid, we notice that we have 4 congruent triangles and 1 square.

Triangles:

The area of a triangle is denoted as A = (1/2) * b * h, where b is the base and h is the height. Here, the base is 8, so b = 8, and the height is 6, so h = 6. Plug these values in to get the area of one triangle:

A = (1/2) * b * h

A = (1/2) * 8 * 6 = (1/2) * 48 = 24

The area of one triangle is 24 square units, so the area of 4 is 24 * 4 = 96 square units.

Square:

The area of a square is denoted by: A = s * s = s². Here, s = 8, so plug that in:

A = s²

A = 8² = 8 * 8 = 64

The area of the square is 64 square units.

Now add up the areas of the triangles and square:

96 + 64 = 160 square units

The surface area is 160 square units.

160

Step-by-step explanation:

Surface area = 4 triangles + square

4(½ × 6 × 8) + 8²

96 + 64

160 units²

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
