Find the total surface of this cuboid
5
4
6

Given:

Consider the dimensions of the cuboid are 5 by 4 by 6.

To find:

The total surface of the cuboid.

Solution:

The total surface area of a cuboid is:

Where, l is length, w is width and h is the height.

Substituting l=5, b=4 and h=6, we get

Therefore, the total surface area of the cuboid is 148 sq. units.

d.192

step-by-step explanation:

12*16=192

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
