See attached diagram

Box B

Step-by-step explanation:

To determine the box which is made with less cardboard, we calculate the Total Surface Area of each box.

Rectangular Prism(Box A)

Total Surface Area=2(LW+LH+WH)

=2(10x4+10x3+3x4)

= 2(40+30+12)

=2(82)

Total Surface Area of Box A = 164 square inches

Triangular Prism (Box B )

Total Surface Area=2(Area of Triangle)+Area of Base rectangle+2(Area of side rectangles)

=2(0.5X3X8)+(8X6)+2(5X6)

=24+48+60

=132

Total Surface Area of Box B = 132 square inches

Since the total surface area of Box b is lesser,Box B is made with less cardboard .
