So the bases are 2 squares [4 x 4], and faces are 4 rectangles [4 x 1].
Add together for 32 + 16 = 48 square units.

2*(2*1 + 1*8 + 8*2) = 2*(2 + 8 + 16) = 2*26 = 52 sq ft
A rectangular prism.
A prism is a three-dimensional solid with two parallel bases, or faces, that are congruent.[1] The shape of the base determines what type of prism you have, such as a rectangular or triangular prism. Because it is a 3D shape, finding the volume (space inside) of a prism is a common task; however, sometimes you will need to find the height of a prism. Finding the height is possible if you have enough information already given: either the volume, or the surface area and perimeter of the base. The formulas described in these methods can work for prisms with bases of any shape, provided you know the formula for finding the area of that shape.
A rectangular pyramid you use 1/3 or divide 3 in the product but a triangular prism you use 1/2 or divide 2 on the product.
Three: 1) The area of the cross-sectional rectangle end 2) The area of the rectangle joining the longer side of the cross-sectional rectangular ends 3) The area of the rectangle joining the shorter side of the cross-sectional rectangular ends Then the surface area of the rectangular prism is twice the sum of these three areas.

Surface area of rectangular prism: 2(25)+4(30) = 170 square inches
If each dimension is increased by x% (a multiple of 1+x/100), then the surface area is increased by a multiple of (1+x/100)2. So doubling the length (x = 100) quadruples the area.
1/3 bh x h divided by 2 It depends on the dimensios of the cuboid (rectangular prism). If it has edge lengths a,b and c then it is made of three pairs of rectangles of area ab, ac and bc. So suface area = 2(ab + bc + ca)
2*(2*1 + 1*8 + 8*2) = 2*(2 + 8 + 16) = 2*26 = 52 sq ft
A rectangle has 4 faces: 2 long faces and 2 short faces.
