Asealed rectangle or box measuring 8×6*18 contains 864 sugar cubes each measuring 1×1×1. how many sugar cubes are touching the box

Since the rectangular box is sealed; the cubes touch the 6 sides of the cuboid.

Total number of cubes that touches the inner surfaces of the box are:

2(18 × 8) + 2(8 × 6) + 2(18 × 6)

288 + 96 + 216 =  600 cubes.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
