The formula for the surface area is 2(lw + lh + wh). So all you have to do is plug the values in.
Box A:
2(lw + lh + wh)
2( (4x6) + (4x25) + (6x25) ).
2(24+100+150)
2(274)
548=Surface Area
Box B:
2(lw + lh + wh)
2( (9x5) + (9x11) + (5x11) ).
2(45+99+55)
2(199)
398=Surface Area
Box C:
2(lw + lh + wh)
2( (10x5) + (10x8) + (5x8) ).
2(50+80+40)
2(170)
340=Surface Area
Answer:
The volume of the new crate is exactly 174.4% of the old crate.
Step-by-step explanation:
Volume of a rectangular prism:
The volume of a rectangular prism of dimensions x, y and z is given by:
She decided that the dimensions of the new crate needs to be increased by 40% of the original length.
Each dimension is increased by 40%, which means that each is multiplied by 1 + 0.4 = 1.4. So
Percentage:
The new volume is 2.744 the original volume. Considering the original volume is 100% = 1, it increased by 2.744 - 1 = 1.744 = 1.744*100% = 174.4%.
The volume of the new crate is exactly 174.4% of the old crate.
