Calculate Surface Area: 25cm Square Base Rectangular Prism with 3cm Height

Question

A rectangular prism has a square base measuring 25 cm.

It has a height is equal to 3 cm.

Calculate the surface area of the rectangular prism.

00:00 Find the surface area of the box

00:03 This face is a square according to the given data, so the sides are equal

00:10 We'll use the formula for calculating a square (side times side)

00:16 We'll substitute appropriate values according to the given data, and solve to find side A

00:26 This is the side length

00:31 Now we'll use the formula for calculating the surface area of a box

00:37 2 times the sum of face areas

00:47 We'll substitute appropriate values and solve to find the surface area

01:41 And this is the solution to the question
